Tried that already... :( I patched 2.4.21-pre3 kernel and tried with the
newest 2.4.21-pre4. The weirdest thing is that ACPI works without issues,
only that it blocks USB from working properly (mouse, ramdisk,
everything).
I tried to change BIOS settings as well (automatic IRQ mapping) because
takeover fails and this is supposedly BIOS problem. Unfortunatelly, this
didn't help either. I am considering on upgrading BIOS firmware if I can
find one, but I still don't believe it's BIOS who gives me headache, I
still think it's ACPI driver.

Does anyone else experience inability to restart/shutdown linux automati-
cally if ACPI isn't compiled into the kernel? It just hangs immediately
after "Restarting System". :( This is very frustrating for laptops, which
get turned on/off frequently.

Thanks very much for your answer and your effort, Yuhanes! :)
