I found this oops in the log this morning. Rather than i386 I am running x86_64, and hope this is the right place for this notification. I can find no triggering event, and the computer appears to have recovered gracefully.

Nic, completely unrelated trace to this bug. You also have the binary nvidia module loaded, which makes your problem impossible to diagnose.
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which may contain a fix for your problem. Please update to this new kernel, and report whether or not it fixes your problem. If you have updated to Fedora Core 4 since this bug was opened, and the problem still occurs with the latest updates for that release, please change the version field of this bug to 'fc4'. Thank you.
