oops with 2.4.5-ac12

oops with 2.4.5-ac12

[Walter Hofmann]

I got the following oops with 2.4.5-ac12 after I issued "rmmod -a"
twice. I only notices the oops after I issued "rmmod -a" once which
might explan that ksymoops cannot name the module which caused the oops.

This is possibly ALSA-related (although I never had problems with
unloading alsa modules befode).

WARNING: This version of ksymoops is obsolete.
WARNING: The current version can be obtained from ftp://ftp.ocs.com.au/pub/ksymoops
Options used: -V (default)
              -o /lib/modules/2.4.5-ac12/ (default)
              -k /proc/ksyms (default)
              -l /proc/modules (default)
              -m /usr/src/linux/System.map (default)
              -c 1 (default)

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.
