There are current known issues with nForce2/AMD combo. It has to do with a race condition during the C1 disconnect. The solution is to disable APIC, either in the kernel config or by passing apic=off (or noapic, I can't remember) on the kernel command line. Ever since finding out that little gem (and swithcing to 2.6 kernel) my machine has been rock solid stable. I can throw anything at it, and not a single lock up.
Just to throw some weight behind this, this solution has worked for me on several Athlon / nForce servers I've built. I just removed APIC from the kernel completely.

Just out of curiosity, how does removing APIC support (or disabling it in the BIOS) affect performance? What does an APIC do on a single processor machine? I understand the point in an SMP setup, but not in single processor.
