AMD XP2000+ on ASUS board. With X, KDE, and many many other libs. I keep in sync with FreeBSD-STABLE, as you can see, and last compiled 
11/2/2003 @ 4pm.. I had CVSup'd just before compiling.

Not sure, first time it's happened. I'll keep my eye out for the same problem, and compile a debugging kernel upon request.

 	Sorry for the delay, forgot to fix the address and didn't see the
 email. I haven't gotten the problem again, so I'm guessing it was a freak
 occurance. Also, 2 days later, I recompiled the kernel, so maybe it was an
 error between the 2nd->9th. Feel free to close the PR. Thanks,
 		John
