Here is a similar oops report from 2.4.20-pre10aa1.
ksymoops 2.4.5 on i686 2.4.20-pre10aa1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-pre10aa1/ (default)
-m /boot/System.map-2.4.20-pre10aa1 (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.

1 warning issued. Results may not be reliable.
The mainline (2.4.20-pre10) does not exhibit this issue. Unlike
2.4.20-pre8aa1, 2.4.20-pre10aa1 rebooted itself after the above oops.
I am hoping some of these oops might reveal the real issue/reason/bug to
kernel developers one of these days.
And my sincere thanks for your help.
