Linux tantale 2.4.20-pre11 #1 SMP Tue Oct 15 21:37:01 PDT 2002 i686 unknown

which is a dual-PPro box.

ksymoops 2.4.5 on i686 2.4.20-pre11.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20-pre11/ (default)
     -m /boot/System.map-2.4.20-pre11 (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.
