-===Causes===
+==Affected Models==
 Anomaly in the way the kernel driver handles the i8042 keyboard/mouse controller in the R31.

 These messages in dmesg seem to be related:

-===Workarounds===
+==Workarounds==
 Don't query the battery.  Remove any battery applets from your panel.
-===Partial Solution===
+==Partial Solution==
-Use the following kernel parameter, without quotes, at boot: "i8042.nomux=1". Add this to your "append=" line in lilo.conf or append it to the kernel line in the menu.lst of your grub configuration.
+Use the {{bootparm|i8042.nomux|1}} kernel parameter at boot. Add it to your <tt>append</tt>line in {{path|/etc/lilo.conf}} or append it to the <tt>kernel</tt> line in the {{path|/boot/grub/menu.lst}} file of your grub installation.
 '''Make sure to use ACPI''', as this does not work if you boot with APM.

 ===Undiagnosed problems===
-The problem seems to have returned to my system every since I upgraded to gnome 2.12 and starting running hal/dbus.  Perhaps one of those components is querying my battery.  If anyway one has any suggestions, please post!
