I've seen this oops report before, but since nobody's posted a fix for it or
anything, I figured I'll post the one I saw. I got a series of two oopses after
untarring a 200MB tarfile. (The system has 512MB of memory and was recently
booted into 2.4.21-pre3-ac4).  Here they are, plus boot-dmesg at the bottom.

Kernel was compiled with gcc 2.95.3.
