[1.] One line summary of the problem:    
Kernel 2.4.0-test10 Multiple oops

[2.] Full description of the problem/report:
When running dselect from Debian Woody, after all the packages were
downloaded, it began to install them, and then oopsed twice. The system
seemed normal after words, but would not compile ksymoops, so I had to
reboot to compile/run it.

[3.] Keywords (i.e., modules, networking, kernel):
2.4.0-test10 oops

[4.] Kernel version (from /proc/version):
Linux version 2.4.0-test10 (root@toy) (gcc version 2.95.2 20000220 (Debian
GNU/Linux)) #3 Wed Nov 1 23:29:21 EST 2000

I was on tty1 when the oops happened. I was running the beta Debian XF4 at
the time, and most likely had the tdfx module loaded.
