oops with 2.4.21

[Chris Stromsoe]

I have a machine running 2.4.21 that has been crashing relatively
regularly.  The following oops appeared in the logs this morning, shortly
before the machine locked up.  ver_linux and ksymoops out are below.

Prior to reboot, the console showed

Code: Kernel BUG in header file at line 66
Kernel BUG at panic.c: 141!

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

cbs@tomato:~ > ksymoops < oops
ksymoops 2.4.5 on i686 2.4.21.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21/ (default)
     -m /boot/System.map-2.4.21 (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.
