The below oops seems to happen randomly while in XFree86 (4.1.0),
generally after several hours of X running.  I have a VIA KT266A
motherboard + Athlon XP.  I'm running Debian sid with 2.4.18-pre3 +
Robert Love's preempt patch.

I'd be happy to provide any other pertinent information.  Please CC me
in replies as I'm not subscribed.  Thanks!
