Thanks. Unfortunately that did not fix the problem.
I was able to reproduce 4 more oops. (all happened one after other)
ksymoops 2.4.5 on i686 2.4.20-pre8aa2-p1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-pre8aa2-p1/ (default)
-m /boot/System.map-2.4.20-pre8aa2-p1 (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.

I am able to easily reproduce the issue by doing:
1. Login to XFree86/Gnome or KDE
2. Run Mozilla, Open Office Writer/Impress/Calc and exit all of them
3. mke2fs -j /dev/hda9 (that is a blank 2.5 GB partition)
4. mount /dev/hda9 /test
5. cd /test; dd if=/dev/zero of=zero bs=1024 count=1048576
6. Log out and Log in XFree86
7. Oops appears in the System logs
