Hello,

acpi=off does not make any difference. Yesterday I compiled a 2.5.25 kernel 
and got some more info: during boot, the warning message
i8042.c: Couldnt get IRQ1 for KBD0
(or similar, the messages passed by quickly and, of course, scroll lock didn?t 
work:-) appeared.

Plus, I have got a correction concerning the BIOS warning after reboot:
> > warns about "No interrupts from keyboard 0" and the BIOS
Actually, the warning is "No interrupts from TIMER 0." As a sidenote, the BIOS 
in question seems somewhat broken. It reports overlapping MTRR regions and 
sets the PCI cache line size incorrectly, according to the kernel. 
Furthermore it reports bad refresh rates for my TFT display to the X server. 
After all, I wouldn?t be surprised if this all relates to the f*cked up BIOS 
(it is some "Insyde BIOS 1.07").

If it helps, I can go down the kernel versions to locate the version where it 
broke.

Greetings,

Stefan Winter
