===Software Suspend 2 - swsusp2===
Software Suspend 2, sometimes also called "swsusp2" and "suspend2", is an implementation of suspend-to-disk functionality in the form of a Linux kernel patch and several userspace utilities. It is an alternative to both the BIOS-driven hibernation feature found on most ThinkPad models, and the [[swsusp]] "software suspend" functionality built into recent Linux kernels.
|}

==Features==
Compared to the alternatives, Software Suspend 2 has some unique [http://suspend2.net/features features]:
* Saving the memory image into a swap file, a swap partition or a normal file on any filesystem.
* Cancelling a suspend in progress.
* Different bugs -- if the alternatives don't work, try this one!

It also have the following advantages over [[swsusp]] (these features are also provided, in principle, by the not-yet-stable [[uswsusp]]):
* The ability to compress the memory image as it is written to disk, thereby reducing suspend and resume times.
* Control over amount of RAM written to disk -- can (optionally) discard cached disk blocks to reduce suspend and resume times.
* Textual and graphical UI (optional).

Since it is implemented purely in software, Software Suspend 2 is in principle machine-independent and should work on all modern ThinkPad models. However, in some cases problematic drivers need to be unloaded before suspension. This is handled by the <tt>hibernate</tt> script (see below).

==Installation Instructions==
The [http://suspend2.net/ project home page] has a detailed HOWTO and FAQ. The following are just a few highlights.

===Modifying the initrd generation scripts, and recreate initrd===
If your systems uses an <tt>initrd</tt> file (most do), you'll need to patch or replace your <tt>initrd</tt>-creation script.

*{{Fedora}} 4: in {{path|/sbin/mkinitrd}}, find this line:
echo "echo Mounted /proc filesystem" >> $RCFILE
and add the following immediately afterwards:
echo "echo > /sys/power/suspend2/do_resume" >>$RCFILE
*{{Fedora}} 5: in {{path|/sbin/mkinitrd}}, find this line:
if [ -z "$noresume" -a -n "$swsuspdev" ]; then
and add the following immediately ''before'' the above:
emit "echo 1 > /sys/power/suspend2/do_resume"
You can also use the [http://atrpms.net/dist/fc5/mkinitrd-suspend2/ mkinitrd-suspend2] package from atrpms.
*{{Debian}}: If your system uses mkinitrd to create the initrd, copy [http://dagobah.ucc.asn.au/swsusp/2.0.0.102/swsusp-initrd.sh swsusp-initrd.sh] script to your {{path|/etc/mkinitrd/scripts}} directory before creating initrd image. If you use initramfs-tools, put a similar script into {{path|/etc/initramfs-tools/scripts/local-top/}} (the manpage of initramfs has templates of example "boot scripts")

In any case, make sure you regenerate your <tt>initrd</tt> file by reinstalling the kernel package or explicitly with mkinitrd or mkinitramfs commands.

===Hibernate script===
Software Suspend 2 works best with the <tt>hibernate</tt> script (available from the project home page), which takes care of auxiliary tasks needed on many systems (e.g., unloading problematic modules and restoring video modes).

====Availability====
*{{Gentoo}}: emerge hibernate-script
*{{Fedora}}: kernel and hibernate RPMs are available at http://mhensler.de/swsusp/
*{{Ubuntu}}: packages for Ubuntu Dapper Drake (kernel, hibernate, suspend2ui-userui): http://dagobah.ucc.asn.au/dapper-kernels/
*{{Ubuntu}}: experimental packages for Ubuntu Edgy Eft (kernel, hibernate, suspend2ui-userui): http://3v1n0.tuxfamily.org/dists/edgy/suspend2/
*PLD: poldek -iv hibernate
*Other: check the home page for packages (deb, i386 rpm, tgz, and source rpm) from http://www.suspend2.net

==Configuration tips==
=== Crash fix ===
To avoid pages being resaved during suspend use kernel 2.6.19.2 and suspend2 2.2.9.1 (not stable yet)
OR add the following to
{{path|/etc/hibernate/suspend2.conf:}}
ProcSetting full_pageset2 1
===RediSafe-like functionality===
The hibernate functionality on some ThinkPad BIOSes offers the useful "RediSafe" feature, which suspends to both RAM and disk. This way you get quick resumes (directly from RAM), plus the safey of suspend-to-disk in case the battery runs out.

Software Suspend 2 provides this feature too; simply add the following to {{path|/etc/hibernate/suspend2.conf}}:
PowerdownMethod 3

===Be aware of possible filesystem corruption scenarios===
Certain usage scenarios can cause filesystem corruption with suspend2. Some details on this are in [http://www.suspend2.net/HOWTO-4.html#ss4 the project's HOWTO]. None of the workaround configurations fix the problem satisfactorily, so be warned. In particular, with an ext3 root filesystem, if you suspend to swap partition, and then use sysrescCD/Knoppix/some other way to mount the root filesystem read-only, you risk data corruption when you try to resume from the suspended image.

As far as possible, after suspending the system, don't touch the root filesystem unless you are resuming from it :)
