nForce lockups
The nForce lockup problem has been around for a while now. I have spent the better part of a month trying to fix it. It is making my system virtually unusable-and making me wonder if nVidia deserves its reputation as a Linux-friendly company.
These are the "fixes" I have used: setting idle=pass, not compiling ACPI into the kernel, setting mem=nopentium, setting acpi=off. Then only unimplemented fix I have heard about is using hdparm to change a UDMA setting, but I'm not sure how to do this.

Has anybody solved this problem? How?

Re: nForce locups
I fixed mine by disabling the CPU Disconnect function in the BIOS. This is on ABit NF7-S and AN7 boards.

Another fix that worked before I did the above was:

Compile the kernel with absolutely no APIC or ACPI support.
Specify the kernel line options acpi=off noapic noioapic

Good luck,

Re: nForce locups
I am using an Abit NF7-S. I disabled CPU disconnect, and set my UDMA settings to UDMA3 (with hdparm -X udma3 /dev/hda). Things are working OK right now, no lockup so far. I am going to test it (with grep, which usually caused the lockups), then turn off workarounds one by one until the problem returns; I want to know what is causing this exactly. Thank the Linux gods for a journaling filesystem (each lockup requires a hard reboot).
