PS/2 Keyboard is dead after resume.

PS/2 Keyboard is dead after resume.

[Andrew Haninger]

Hello.

I'm using Linux Kernel 2.6.12.2 plus suspend 2.1.9.9 and acpi-20050408
with the hibernate-1.10 script. My machine is a Shuttle SK43G which
has a VIA KM400 chipset with an Athlon XP CPU.

Suspension seems to work well. However, when I resume, the keyboard is
dead and there is a warning in dmesg before and after suspension:

atkbd.c: Spurious ACK on isa0060/serio0. Some program, like XFree86,
might be trying access hardware directly.

This machine doesn't have XFree86 on it.

I am presuming that this is a bug since I've used the exact same
kernel+patches (with hibernate 1.09 script) on another machine without
issues. I'm not sure if it's a suspension bug or if it's a kernel bug
that is brought to light by the suspend2 patches. If I'm wrong and
I've made a mistake, I'd love to hear it.

Thanks.

Could you try doing:

	echo 1 > /sys/modules/i8042/parameters/debug

before suspending and the post your dmesg, please? Maybe we see something
there.

Ok, so you start with IRQ 12 disabled.. You don't have a PS/2 mouse,
do you?

You did not select PNP support (but as far as keyboard controller settings
go we don't trust it anyway on i386).

And here you have a bunch of hardware gets assigned to IRQ 12...
Hmm, I tought ACPI would try not use 12 unless it is absolutely
necessary. What appens if you use "pci=routeirq" boot option?

Keyboard seems to be resumed just fine...

But when we try to talk to mouse port we ket response from the keyboard
and something gets confused.

You can try working around this with "i8042.noaux" kernel boot option,
but we should probably teach i8042 driver to not touch AUX port on resume
if it was disabled.

I've never ever found it to work, so I usually disable it.

The keyboard was still dead after resume.

This worked. Strangely enough, after googling for i8042 and suspend
last night, I found the 2.6.12 kernel boot options file. I tried
i8042.nomux, i8042.direct, and some others, but nothing worked. Just
for fun, I tried booting without any kernel boot options (just the
suspend2 option) and with a PS/2 mouse plugged in. On suspend, the
keyboard worked.

Maybe this could/should be added to the suspend2 code as well?

Whatever. It works for now. If you'd like any more information, just
let me know. Thanks!
