Third OOPS report and ksymoops output 2.4.20

[David Lewis]

Here is another one from the same machine. If this is not the place to be
posting these please let me know. The list FAQ indicated that posting these
is appropriate, but I have not seen any responses which leads me to believe
that it is not the correct place.

ksymoops 2.4.5 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /boot/System.map-2.4.20 (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.
