Network related oops

[Andrew Ryan]

Maybe this has been fixed in pre6/7, but here is a dump of a recent crash I
had on one of our systems.  There were NO modules loaded.

ksymoops 2.4.0 on i686 2.4.20-pre5.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-pre5/ (default)
     -m /boot/System.map-2.4.20-pre5 (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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
