Hey,

Posted an oops last week, with an older rh kernel, upgraded, as per alans 
advice, and now found this in dmesg.

If theres anything you need me to do, please cc

thanks,

	/ Brett

ksymoops 2.4.1 on i686 2.4.9-13.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.9-13/ (default)
     -m /boot/System.map-2.4.9-13 (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.
