kernel bug report [2.4.20-pre7]

I don't know where to send this bug report therefore I send it here as I
found advise in "oops-tracing.txt".

The bug caused during iptables rules start process.
Maybe this report will be usefull.

ksymoops 2.4.6 on i686 2.4.20-pre7. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-pre7/ (default)
     -m /boot/ (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.
