Problems with ACPI suspend-to-ram

2009-03-23T10:57:11Z

Chihchun: /* Troubles on resume */

The following glitches may or may not occur in relation to suspending to RAM:

==Troubles on suspend==
;Permissions:If your suspend is failing, and a {{cmdroot|tail /var/log/acpid}} shows "Permission denied" errors, be sure that your new ACPI event and action scripts have the appropriate permissions.

;Write error:If {{cmdroot|echo mem > /sys/power/state}} shows "write error: Operation not permitted", verify that CONFIG_HOTPLUG_CPU option is enabled in the kernel. [[Software_Suspend_2|Suspend2]] automatically selects this option.

;Broken sysfs interface:You may experience problems when using {{cmdroot|echo standby > /sys/power/state}} or {{cmdroot|echo mem > /sys/power/state}} (machine goes to sleep and wakes up immediately). This can be avoided by using {{cmdroot|echo -n 3 >/proc/acpi/sleep}} to get it to sleep. This can be also happen if hotplug daemon is still running or if the usb hcd modules are still loaded.

;Immediate Resume after Suspend:If a resume starts a few seconds after suspend a reason might be the USB modules. Unload the modules uhci_hcd and ehci_hcd before you suspend. Users of hibernate-scripts add "UnloadModules uhci_hcd ehci_hcd" to {{path|/etc/hibernate/common.conf}}.

;Hangs on "switching to UP code":You may be using a [[How to make use of Dynamic Frequency Scaling|frequency scaling governor]] such as "conservative" or "ondemand", which sometimes have problems with suspending. Switching to a governor such as "powersave" or "performance" before suspending may solve this problem.

;MySQL daemon running:If you're running MySQL, sleep may also not work, so stop MySQL first, then sleep. Remember to restart MySQL when you wakeup.

;LCD backlight remains on during sleep:When your system is equiped with a Radeon Mobility graphic controller your [[Problem with LCD backlight remaining on during ACPI sleep|LCD backlight may not turn off automatically]]. Use [[radeontool]] to switch off your backlight prior suspend in your sleep action script.

;High power drain during sleep:Also, you might want to take note of the [[Problem with high power drain in ACPI sleep]].

;Built-in MMC reader:If you have an MMC reader, and the computer hangs when attempting suspend then remove sdhci, mmc_block, and mmc_core modules before suspending.

;Could not power down device <NULL>: error -22:If you have the acpi_cpufreq kernel module loaded, this prevents suspension.

;Immediate Resume, but Suspend "moon" light continues to flash:???

;Hard system lock up:If you are using savagefb, make sure to [[Problem_with_unusable_console|disable the "Console Acceleration" option]] (CONFIG_FB_SAVAGE_ACCEL) in the kernel config. Otherwise, susped-to-RAM may lock up your system such that you must remove the AC adapter and battery to get it to boot again.

;Hard system lock up 2: If you are using a Thinkpad G40 and Ubuntu (this problem experienced on 8.04), you may experience problems with ACPI when opening your laptop lid that freezes the system. You can disable ACPI in your kernel parameters, or modify {{path|/etc/acpi/lid.sh}} to switch to a plain text console on close and back to Gnome/KDE on open (use {{path|/usr/bin/chvt 1}} and {{path|/usr/bin/chvt 7}}, respectively)

;Solid 'moon' but fans still spinning: On a T61p with an nvidia quadro 570M, you might experience a near-complete suspend, with the backlight turned off, unresponsive usb, and a solid 'moon' lit, however system fans are still going. The proprietary nvidia module is to blame. On gentoo, appending "NVreg_Mobile=3" to the 'option' line in /etc/modules.d/nvidia fixed the issue for me. On other distros, look in your module autoloading conf file

==Troubles on resume==
;Blank display on resume:
:When resuming from a suspend-to-ram the display might remain black (on {{X60}}) or might only show the pre-suspend output (the system is still rebootable via {{key|ctrl}}{{key|alt}}{{key|del}}). See [[Problem with display remaining black after resume]] for solutions. See also '''System hang on resume''' on this page - which may be potentially mismatched with this one.

;No mouse cursor on resume:
:When resuming from a suspend-to-ram your X cursor might be invisible(on {{X40}}) when using {{path|/sys/power/state}} directly to suspend, they way to fix this is to rerun the post bios code after returning for suspending.
:{{cmdroot|FGCONSOLE<nowiki>=</nowiki>`fgconsole\`}}
:{{cmdroot|chvt 1 && echo -n mem >/sys/power/state}}
:{{cmdroot|vbetool post && chvt 7 && chvt $FGCONSOLE}}

;Garbage on text consoles on resume:When resuming from suspend-to-ram the text console displays may show garbage instead of actual text. The machine is otherwise still responsive and X displays fine. If all of this is true, then adding the kernel option {{bootparm|acpi_sleep|s3_bios,s3_mode}} in your menu.lst or lilo.conf may solve the problem.

;Broken hardware support after resume:
:*The '''serial port''' of the port replicator might not work after resume.
:*The '''parallel port''' might not work after resume. A possible fix is to unload and reload the parallel port drivers: {{cmdroot|rmmod lp parport_pc parport; modprobe lp}}.
:*Problems with the '''CD-RW/DVD drive''' after wake up from ram have been experienced.
:*There is a known Problem regarding '''battery info''' after suspend to RAM. A [http://www.ussg.iu.edu/hypermail/linux/kernel/0511.0/2429.html small patch] exists for kernels 2.6.14/2.6.15.
:*On {{X20}} and {{X21}} (and possibly other) models, the '''sleep LED''' is not reset properly on resume and will keep blinking. If you have the [[ibm-acpi]] kernel module loaded with the {{bootparm|ibm-acpi.experimental|1}} option, you can switch it off on resume by appending the following line to your suspend script: {{cmdroot|echo 7 off > /proc/acpi/ibm/led}}

;Crash on resume:
:*When using '''older ATI proprietary drivers''' a crash on resume can be solved by using [http://freshmeat.net/projects/vbetool/ vbetool]. See the example suspend script [[Problem with display remaining black after resume#Solution for ThinkPads with Intel I830 Chipset]]. This is no longer necessary with recent revisions of the ATI proprietary driver.
:*A crash could also be caused by having '''apic support''' enabled in the kernel config. Try disabling it (in the "Processor type and features" section).
:*On machines with Savage chipsets, the '''savagefb framebuffer driver''' might crash the machine on resume. Make sure it is disabled in your kernel config and use the standard vesafb driver instead.
:*SATA-based laptops utilize the '''libata layer for disk access''' which does not have fully-working power-management support before Linux kernel 2.6.16 (ata_piix) and 2.6.19 (ahci). Suspend to RAM crashes these machines on resume. See the [[Problems with SATA and Linux#Hang on resume from suspend to RAM|relevant section]] on the [[Problems with SATA and Linux]] page.
:*Using [[HDAPS]] as a module causes a crash on resume with the Linux kernel 2.6.19 (possibly even earlier versions). This was observed on a {{X41}}. Try unloading the module before suspending.
:*Gnome-power-manager might be using the wrong backend. If you are able to suspend from the commandline with a certain method, make sure the others are not available so that g-p-m doesn't choose the wrong one. For example, if you suspend with {{cmdroot|echo mem > /sys/power/state}}, make sure '''uswsusp''' and '''hibernate''' are uninstalled.

;System hang on resume:
:System hangs immediately upon attempted resume if suspended with USB devices attached to dock. Try using the laptop's own USB ports instead. That fixed the problem for me. Details: https://bugs.launchpad.net/ubuntu/+bug/218760 --[[User:Dave abrahams|Dave abrahams]] 17:45, 28 April 2008 (CEST)
:When system resumes it hangs right after restarting tasks. Strange thing is, that you may be even able to restart your ThinkPad using {{key|ctrl}}{{key|alt}}{{key|del}}, but if you try to blindly exec a command, it will not work, (eg. touch FILE) so it's not only the problem of videocard. This may be fixed by passing {{bootparm|ec_intr|0}} on kernel cmdline. Affected models: {{T20}}, {{T21}} (at least [[2648-46U]] (T20),[[2647-8AG]] (T21)).
:'''Note:''' ''this is resolved in kernel 2.6.20, there is no need to pass the {{bootparm|ec_intr|0}} bootparam anymore (moreover, you are discouraged to use it) See [http://bugzilla.kernel.org/show_bug.cgi?id=6749 revelant kernel bug report]''
:See also [https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/73546 this bug report], I can confirm some strange problems on resume with Bluetooth enabled - my T61 may freeze in a couple of minutes after resuming. This problem is gone as soon as I disable Bluetooth (stop all bluetooth related services and `echo "disable" > /proc/acpi/ibm/bluetooth`).

;Shutdown on resume:
:If your system immediately begins to shut down right after resume, make sure you don't have acpid running with the power button tied to shutdown. The system is simply sensing the power button event and shutting down. This issue has been reported as a bug against the kernel ACPI subsystem, refer to [http://bugzilla.kernel.org/show_bug.cgi?id=6612 kernel.org bugzilla bug #6612].

;Immediate suspend on resume:
:When running GNOME, sometimes gnome-power-manager will put the system back into suspend immediately after resuming. This is caused by a known bug in HAL that causes some ACPI events to be reported incorrectly after a suspend-to-ram. A simple workaround can be found [http://live.gnome.org/GnomePowerManager/Faq?action=recall&rev=28#head-b8b1280115b0a51c2cc27b13a57121130ebf36cb here].
:Note that suspend being triggered by unrelated ACPI events such as disconnecting the AC adapter may also be fixed by the above method.

;Power Off when suspended laptop is docked
:When T60p is suspended, docking laptop into Advanced Dock immediately turns off laptop and crescent moon sleep indicator LED. Pressing power button initiates cold boot. Also reported by multiple people on thinkpads.com.

;SectorIdNotFound disk errors when laptop is resumed
:The errors look like this:
Oct 14 17:35:02 cacharro kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Oct 14 17:35:02 cacharro kernel: hda: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=115896900, sector=115896900
Oct 14 17:35:02 cacharro kernel: ide: failed opcode was: unknown

:This happens when you have [[Hidden Protected Area]] (HPA) enabled on the hard drive. There is a [http://bugzilla.kernel.org/show_bug.cgi?id=6840 kernel bug report with an unfinished patch] to fix this. This is not fixed as of kernel 2.16.18. Adding {{bootparm|libata.ignore_hpa|1}} to the kernel command line might help.

:Update: This is still occuring here on 2.6.26-1-686 on Debian, even though the bug has been marked as fixed in 2.6.22. I will try disabling the HPA to see if the problem is related... [[User:TheAnarcat|TheAnarcat]] 01:51, 20 October 2008 (CEST)

;Resuming a second time does not work after successfully resuming once from suspend-to-ram
This happened to me on my X200: I could resume once, but on the second time, pressing the power button made the HD light flash briefly and then nothing happened anymore. The AC and standby lights stayed on and I had to shut the computer down by keeping the power button pressed.
A workaround is to disable the Intel TXT feature in the BIOS. You can find it in the "Security" section.

:*On {{X20}} and {{X21}} (and possibly other) models, the '''sleep LED''' is not reset properly on resume and will keep blinking. If you have the [[ibm-acpi]] kernel module loaded with the {{bootparm|ibm-acpi.experimental|1}} option, you can switch it off on resume by appending the following line to your suspend script: {{cmdroot|echo 7 off > /proc/acpi/ibm/led}}

;Crash on resume:
:*When using '''older ATI proprietary drivers''' a crash on resume can be solved by using [http://freshmeat.net/projects/vbetool/ vbetool]. See the example suspend script [[Problem with display remaining black after resume#Solution for ThinkPads with Intel I830 Chipset]]. This is no longer necessary with recent revisions of the ATI proprietary driver.
:*A crash could also be caused by having '''apic support''' enabled in the kernel config. Try disabling it (in the "Processor type and features" section).
:*On machines with Savage chipsets, the '''savagefb framebuffer driver''' might crash the machine on resume. Make sure it is disabled in your kernel config and use the standard vesafb driver instead.
:*SATA-based laptops utilize the '''libata layer for disk access''' which does not have fully-working power-management support before Linux kernel 2.6.16 (ata_piix) and 2.6.19 (ahci). Suspend to RAM crashes these machines on resume. See the [[Problems with SATA and Linux#Hang on resume from suspend to RAM|relevant section]] on the [[Problems with SATA and Linux]] page.
:*Using [[HDAPS]] as a module causes a crash on resume with the Linux kernel 2.6.19 (possibly even earlier versions). This was observed on a {{X41}}. Try unloading the module before suspending.
:*Gnome-power-manager might be using the wrong backend. If you are able to suspend from the commandline with a certain method, make sure the others are not available so that g-p-m doesn't choose the wrong one. For example, if you suspend with {{cmdroot|echo mem > /sys/power/state}}, make sure '''uswsusp''' and '''hibernate''' are uninstalled.

;System hang on resume:
:System hangs immediately upon attempted resume if suspended with USB devices attached to dock. Try using the laptop's own USB ports instead. That fixed the problem for me. Details: https://bugs.launchpad.net/ubuntu/+bug/218760 --[[User:Dave abrahams|Dave abrahams]] 17:45, 28 April 2008 (CEST)
:When system resumes it hangs right after restarting tasks. Strange thing is, that you may be even able to restart your ThinkPad using {{key|ctrl}}{{key|alt}}{{key|del}}, but if you try to blindly exec a command, it will not work, (eg. touch FILE) so it's not only the problem of videocard. This may be fixed by passing {{bootparm|ec_intr|0}} on kernel cmdline. Affected models: {{T20}}, {{T21}} (at least [[2648-46U]] (T20),[[2647-8AG]] (T21)).
:'''Note:''' ''this is resolved in kernel 2.6.20, there is no need to pass the {{bootparm|ec_intr|0}} bootparam anymore (moreover, you are discouraged to use it) See [http://bugzilla.kernel.org/show_bug.cgi?id=6749 revelant kernel bug report]''
:See also [https://bugs.launchpad.net/ubuntu/+source/acpi/+bug/73546 this bug report], I can confirm some strange problems on resume with Bluetooth enabled - my T61 may freeze in a couple of minutes after resuming. This problem is gone as soon as I disable Bluetooth (stop all bluetooth related services and `echo "disable" > /proc/acpi/ibm/bluetooth`).

;Shutdown on resume:
:If your system immediately begins to shut down right after resume, make sure you don't have acpid running with the power button tied to shutdown. The system is simply sensing the power button event and shutting down. This issue has been reported as a bug against the kernel ACPI subsystem, refer to [http://bugzilla.kernel.org/show_bug.cgi?id=6612 kernel.org bugzilla bug #6612].

;Immediate suspend on resume:
:When running GNOME, sometimes gnome-power-manager will put the system back into suspend immediately after resuming. This is caused by a known bug in HAL that causes some ACPI events to be reported incorrectly after a suspend-to-ram. A simple workaround can be found [http://live.gnome.org/GnomePowerManager/Faq?action=recall&rev=28#head-b8b1280115b0a51c2cc27b13a57121130ebf36cb here].
:Note that suspend being triggered by unrelated ACPI events such as disconnecting the AC adapter may also be fixed by the above method.

;Power Off when suspended laptop is docked
:When T60p is suspended, docking laptop into Advanced Dock immediately turns off laptop and crescent moon sleep indicator LED. Pressing power button initiates cold boot. Also reported by multiple people on thinkpads.com.

;SectorIdNotFound disk errors when laptop is resumed
:The errors look like this:
Oct 14 17:35:02 cacharro kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Oct 14 17:35:02 cacharro kernel: hda: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=115896900, sector=115896900
Oct 14 17:35:02 cacharro kernel: ide: failed opcode was: unknown

:This happens when you have [[Hidden Protected Area]] (HPA) enabled on the hard drive. There is a [http://bugzilla.kernel.org/show_bug.cgi?id=6840 kernel bug report with an unfinished patch] to fix this. This is not fixed as of kernel 2.16.18. Adding {{bootparm|libata.ignore_hpa|1}} to the kernel command line might help.

:Update: This is still occuring here on 2.6.26-1-686 on Debian, even though the bug has been marked as fixed in 2.6.22. I will try disabling the HPA to see if the problem is related... [[User:TheAnarcat|TheAnarcat]] 01:51, 20 October 2008 (CEST)

;Resuming a second time does not work after successfully resuming once from suspend-to-ram
This happened to me on my X200: I could resume once, but on the second time, pressing the power button made the HD light flash briefly and then nothing happened anymore. The AC and standby lights stayed on and I had to shut the computer down by keeping the power button pressed.
A workaround is to disable the Intel TXT feature in the BIOS. You can find it in the "Security" section.

Chihchun:

I have the ThinkPad X200, and I was wondering if anybody had success with hibernate, sleep, and general power saving?

Also, can anybody find the right framebuffer module and configure it for the 1200x800 screen resolution?

== See my Fedora 9 on X200 article ==

I am now running Fedora 10-Alpha/rawhide on my X200 and everything basically functions (gigabit ethernet, 5100AGN wireless, webcam) except I have to use the vesa driver with xorg.conf instead of the i810 which causes machine crashes. (Apparently it is a known bug upstream and I'm just hoping for some newer xorg-x11-drv-i810 to try out from rawhide). You can set a 1280x800 mode in xorg.conf with the vesa driver.

:Hmm... I run debian testing so I may or may not be able to help, but it appears that at least in X in debian, all the intel chips have been integrated into an 'intel' video driver, which works fine for me. The question about the 1200x800 mode was just for setting it in the framebuffer. Also, it appears that the option to disable HV expansion in BIOS has disappeared, has it not?

:Hibernate and sleep have the problem of immediately resuming—I don't believe any of the workarounds I found on the ACPI page have any effect.

:--[[User:Harrisonts|Harrisonts]] 08:09, 2 October 2008 (CEST)

::Hibernate works well with me. Suspend has the backlight issue. The resume is ok but the screen is dark. In fact on certain angles it is possible to see the image displayed...

::--[[User:rdemaria|rdemaria]] Mon Nov 10 19:43:59 EST 2008

::I mentioned i810 but that is just the package name on Fedora which includes the "intel" driver which is being loaded to operate the card when I tried it. It works after reboot but crashes after suspend/resume and hibernate/resume and there is a bug in the Fedora bugzilla (for rawhide/Fedora 10) already with multiple reporters for Thinkpad X200 models.

::Rdemaria: Are you using the vesa driver? I think the backlight works after suspend with the vesa xorg driver, if the i915 kernel module is loaded so it handles power management... however, I have not done enough cycles to be sure everything is reliable. I still have crashes on resume if I use the intel xorg driver. I use vesa and have modprobe i915 in my rc.local.
::: Yes it works!!!
:::--[[User:rdemaria|rdemaria]] Thu Nov 13 10:59:40 EST 2008

::Harrisonts: I wrote up a hardware issue in the known problems page. I had to have my X200 mainboard replaced, to make it stop resuming immediately from suspend, hibernate, and poweroff actions. It was painful to get through the layers of Lenovo tech support to do this, having to convince each person over again that there was a problem!

== Does the X200 have AMT? ==

Does anyone know whether the X200 has Intel AMT support? I don't see anything in the BIOS or during POST, but I've already destroyed the windows and recovery partitions and cannot check whether there are any other utilities to gain access...

: Hi, Confirmed there is AMT options in BIOS 2.02 (6DET38WW).

== What is the "perfect" desktop kernel .config for the X200? ==

I'm trying to set up the "perfect" kernel configuration for the X200 when hardware is concerned. Questions like whether or not it should be compiled with legacy IDE support spring to mind, as well as how to take out all drivers and options for hardware not found on the box...

I know running a stock distribution kernel is the recommended way, but where's the fun and learning process in that? For those who want a deeper understanding, kernel tweaking seems to be one of multiple answers.

[http://pastebin.ca/1305061 My first attempt at optimal kernel .config]

Since I'm brand new here : Is this the right forum for such a discussion, and is the use of pastebin the appropriate place to share the kernel .config?

==Adding entries==

Click the "Edit" link on the appropriate series above and add an entry of the following form:
:<tt>| </tt>description of your model
:data line 1
:data line 2
:<tt>||</tt>
:<tt>|-</tt>

where the two data lines are generated by the following <tt>bash</tt> command:

<pre>
for X in system-{manufacturer,product-name,version} \
baseboard-{manufacturer,product-name,version} \
chassis-{manufacturer,version} bios-{vendor,version,release-date}; do \
echo -n "|| `sudo /usr/sbin/dmidecode -s $X` "; done; \
sudo /usr/sbin/dmidecode | perl -0777 -ne \
'm/\n(.*).\n.*\n(.*Embedded Cont.*)\n/i; print "\n|| <nowiki><</nowiki>nowiki>$1$2</nowiki>\n"'
</pre>

While at it, you may also want to test [[tp_smapi]] and update its [[tp_smapi#Model-specific_status|model-specific status table]].
