turn on ioapic edge timer--
http://www.kernel.org/pub/linux/kernel/people/bart/2.6.0-test11-bart1/broken-out/nforce2-apic.patch
We're all trying to get acpi, apic, lapic, io-apic working when turned on in cmos/bios and kernel.
The three things that each alone have achieved stability on somebody's system here are 1) bios update 2) cpu disconnect off either in cmos if available or by athcool or kernel patch with same 3) timing delay patch
For CPU disconnect you still need athcool or this one http://www.kernel.org/pub/linux/kernel/people/bart/2.6.0-test11-bart1/broken-out/nforce2-disconnect-quirk.patch
Both patches are for 2.6.0-test11 kernel.
