Subject: [2.6.22] i8042, ACPI, ipw2100 and issues reported by psmouse.c atkbd.c
Kernel: 2.6.22-r5
Kernel option: i8042.nomux=1
See attached full dmesg for more.
I have recently updated my kernel to 2.6.22 and - in the same occasion -
changed various options in the kernel .config; I cannot state that the
problem have arisen since kernel 2.6.22 but more probably since I
enabled ACPI.
My recent configuration changes have been also to xorg.conf (regarding
GLX and AIGLX), but I have no real clue about what is causing the
troubles. It must be a particular combination of kernel options which
triggers this faulty scenario.
The first problem I had to solve was about the mouse, not working properly:
-----
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 - driver resynched.
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 4
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 - driver resynched.

I fixed it adding i8042.nomux=1 in the kernel options.
The problem which still remains, and I can't fix or work it around, is
witnessed by the below dmesg lines:
-----
atkbd.c: Unknown key released (translated set 2, code 0xe0 on
isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.
atkbd.c: Unknown key released (translated set 2, code 0xe0 on
isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.
atkbd.c: Unknown key released (translated set 2, code 0xe0 on
isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.
-----
The release event for some keys is never caught, so all sorts of
troubles happen if for example I use the Del key and it stucks, or if I
use the Ctrl key and it never gets released...pushing again the stuck
key brings back the key in the proper status.
I could not find a pattern for the verification of the problem, it seems
to happen at random.
I /feel/ that this is still an i8042/ACPI chipset issue (note that I
have ipw2100 active when the problem happens; the mouse problem did not
happen when ipw2100 was disabled and I think the psmouse.c lines and
atkbd.c are someway related).
Can somebody please give me some clues about this issue, and possible
solutions? I have been searching the web for a couple of weeks and seems
like it is a common trouble of notebook users, but nobody has yet
published a solution.
Thanks,
