oops in 2.4.17

Hi

The ksymoops output is below

This happened when I started screen after logging in just after
booting. I'm not able to reproduce it. I've had a few hangs recently
on this machine so I'm trying to find out if it's software or
hardware.

ksymoops 2.4.3 on i686 2.4.17.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17/ (default)
     -m /boot/System.map-2.4.17 (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.

Warning (compare_maps): mismatch on symbol partition_name  , ksyms_base says c01f3160, System.map says c01530b0.  Ignoring ksyms_base entry
