I got this OOPS while unloading the ns558 module.. I don't think it did
this in 2.4.0-test8, but I don't recall ever unloading it in test8..
I've attached the ksymoops output..

Zinx Verituse (See headers for gpg/pgp key info)
ksymoops 2.3.4 on i686 2.4.0-test9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.0-test9/ (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.
Warning (compare_ksyms_lsmod): module ns558 is in lsmod but not in ksyms, probably no
symbols exported
