Hello all,

I've experienced an oops with kernel 2.4.25 (stock kernel on a redhat 9
system). The system had been up for over 40 days and wasn't
under any load (it's a webserver that never sees any traffic).
All filesystems are ext3fs.


ksymoops output:

ksymoops 2.4.5 on i686 2.4.25.  Options used
      -V (default)
      -k /proc/ksyms (default)
      -l /proc/modules (default)
      -o /lib/modules/2.4.25/ (default)
      -m /boot/ (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.
