Vojtech, I figured these should be sent to you. If I am wrong, please redirect them to the correct person / list and let us know.

Thank you.

I am having the same problem with my Shuttle FT61 motherboard, although I have not tried to disable ACPI... Until now I thought I just had a faulty keyboard, as my method to fix this was to unplug the keyboard and plug it back in after bootup. When this happens, I see this in dmesg as the last line:

input: AT Translated Set 2 keyboard on isa0060/serio0

I am also having problems with my AUX mouse, as seen in message

Frank, are you having problems with your ps/2 mouse port as well?

I am so glad that you asked this.

I have not been able to get my ps/2 mouse to function with any
2.6.x or 2.4.x kernel (same ASUS MB). The problem is already
so long standing that I have completely given up on it and use
a serial mouse exclusively and no longer bother with ps/2.

(I also hate to report that since I dual boot with MS Windows,
the ps/2 mouse functions properly under the same conditions
with MS Windows 2K. The hardware cannot be at fault.)

As a clarification, I have been having these keyboard problems intermittently, regardless of whether I'm using -mm or mainline kernel. I was NOT having this problem in 2.6.11 I wasn't having the psaux mouse problems in 2.6.11 either .... I unplugged my psaux mouse from that machine before 2.6.12-mainline was released, so I don't know if those symptoms are still present.

Actually, my keyboard problems began with kernel-2.6.11, but were
quickly resolved when I used the following parameter in my lilo.conf


When I use this parameter, or any other i8042 specific parameter,
with kernel-2.6.12, there is no effect. The keyboard still occasionally
comes up dead.

Thanks for the information on unplugging and re-plugging the keyboard.
I'll give that a try soon.

Guys, are these problems fixed in 2.6.13-rc4?

If not, please cc linux-kernel on the reply, thanks.

Sadly, I must report that yes, the problem still intermittently occurs in 2.6.13-rc4 :-( I'm the one that tested on the Shuttle FT61 Motherboard. Never has a problem in windows and never in 2.6.11 and earlier.

I first noticed this problem sometime during 2.6.12-rc series.
