Sorry to ask what is probably a silly question if you know the answer (or where exactly to find the answer) but...

OK, over the weekend I backed up everything on my linux partition, deleted all the files, and then reinstalled everything.  I copied my APT sources list and cache after the base install, so the whole process took well under 24 hours, and I was sleeping for a few of those :)  Hopefully none of the .deb files were corrupted and causing my problem, but I really didn't want to download much on a 28.8.

Since then I've had a few freezes, but of course that doesn't provide any information.  Then today I got some "Oops" messages running BitchX (which of course had been working before, and worked again after I restarted).  So I ran ksymoops on the kernel log in /var/log (I can't remember what it is called, /var/kern.log I think).  This showed that I actually got an Oops yesterday that I didn't notice.
This was the first part of the ksymoops output:
ksymoops 2.4.5 on ppc 2.4.18-powerpc.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.18-powerpc/ (default)
     -m /boot/System.map-2.4.18-powerpc (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.

So apparently I need to specify where to get the symbols.  Something to do with the "-k" option and /var/log/ksymoops, but beyond that I don't know.
