[Bug 25673] Re: Keyboard and touchpad doesn't work after suspend-to-ram on a Fujitsu-Siemens Amilo M1420

[Federico Sassi]

Hi,
sorry for another entry but I forgot to mention my test about booting with different parameter of i8042 as suggested by Kashif Sheikh in a precedent entry in this bug.
I've tried booting with:
i8042.noaux
i8042.reset
i8042.noacpi

It didn't worked in every case but there are little differences in dmesg
outputs

NOACPI
it's exacly like without that booting option, in dmesg there is the same
"i8042: failed to resume active multiplexor, mouse won't work."

NOAUX
there is no line in dmesg after resume telling anything about i8042 and there is only one
"atkbd.c: Unknown key pressed (translated set 2, code 0x0 on isa0060/serio0).
 atkbd.c: Use 'setkeycodes 00 <keycode>' to make it known."

RESET
there is a different statement:
"i8042.c: i8042 controller selftest failed. (0x0 != 0x55)"

Do you know any explanation about this?

Bye

Federico
