*maybe* I found the bugger, at least I got APIC more stable (need to test whether oit is really stable, compiling kernel right now...):

It is a problem with CPU disconnect function. I tried various parameters in bios and turned cpu disconnect off, and tada, I could do several subsequent hdparms and machine is running! As CPU disconnect is a ACPI state, if I am not mistkaen, I think there is something broken in ACPI right now or in APIC and cpu disconnect triggers the bug.

Maybe now my windows environment is stable, as well. It was much more stable with cpu disconnect and apic, nevertheless seldomly locked up.

So gals and guys, try disabling cpu disconnect in bios and see whether aopic now runs stable.

I have an Abit NF7-S Rev2.0 with Bios 2.0.
