oops in __kfree_skb with 2.4.0-ac4

I got the following oops yesterday evening - below is the ksymoops output
of the hand typed oops report.
As the kernel is "relatively" old this oops might not be of much interest.
If someone is interested however, shout, and I will provide more info about
the system etc.
I am going to upgrade to the current kernel now.



ksymoops 2.3.5 on i686 2.4.0-ac4-PII. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-ac4-PII/ (default)
     -m /lib/modules/2.4.0-ac4-PII/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.
