It's virtually an faq that if nforce2 is unstable then you may actually need apic, local apic, ioapic, a bios update, these patches, maybe athcool utility.
My nforce2 motherboard had ERR count and excessive MIS count in /proc/interrupts due to sharing interrupts between two pci cards. I removed the ethernet card, used the motherboard ethernet and forcedeth driver, so I was not sharing interrupts between pci cards, and that gave me ERR 0 and minimal MIS. Shared interrupts might be your problem.
Personally I found that noapic or acpi=off could not do anything for me either. Currently I have pre-emptive kernel, apic, acpi, local apic.
You can try a bios flash update. This is most hopeful for Award bios. Save your old bios just in case when the flash software asks if you want to save your old bios. We heard from one person who needed to go back to his old bios, but several got rid of their nforce2 crashes by a bios update.
You can try athcool utility turning cpu disconnect off--"athcool off". This stopped crashing for a few. I don't need that.
You can try the patches; they can't hurt and would be easy to remove. To make them work you need apic on in bios, apic and local apic on in kernel config.
