Kernel oops report

[Stephen Gran <steve@linuxforce.net>]

Hello all,
I am sorry if this is not the right place to send this, but this is my
first oops report (shows how good you normally are :)

Background - dual k6 box, with raid array and 1 gb RAM.  Fairly busy
webserver, but not significantly loaded (uptime says >1 for all).

If you need any more information, I will be happy to try to help debug
this.  I'm guessing it's a problem in the k6 smp code, but I can't be
sure.

afradm@www01:~$ ksymoops < oops.txt
ksymoops 2.4.5 on i686 2.4.24-xertus-1-k6-smp.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.24-xertus-1-k6-smp/ (default)
     -m /boot/System.map-2.4.24-xertus-1-k6-smp (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.
