SubjectOops Report
First off:

root@damaged:/usr/src/linux/scripts/ksymoops#uname -a
Linux damaged 2.4.0-test2-ac2 #8 Sat Jul 1 10:08:49 CDT 2000 i686 unknown

What I did to make it happen, along with the oops.
root@damaged:~#mount /floppy
root@damaged:~#mc

(In here i had moved a file onto the floppy. It was an Award bios file.)

root@damaged:~#sync
root@damaged:~#umount /floppy

Segmentation fault

ksymoops output is attached as it's a bit long to paste.

Dunno what else to provide...
--
I doubt, therefore I might be.
ksymoops 2.3.4 on i686 2.4.0-test2-ac2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test2-ac2/ (default)
-m /usr/src/linux/System.map (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.
