The following is ksymoops output.

The system in question is an Intel box running 2.2.14, and has had
severe instability problems since mid January. These have persisted
over a near-complete hardware replacement (one original IDE hard drive
remains). Debian distro, Woody.

Typically, the system will report an Oops similar to that below, and
either freeze or crash and reboot at some point, usually several hours,
later. The Oops is almost always reported in rxvt, though other apps
have been reported as well. System uptimes range from 1-14 days,
currently, between crashes.

I've looked at the oops-tracing.txt document
(http://kernelnotes.org/doc22/oops-tracing.txt), but don't know if I can
run gdb against the kernel as I don't seem to have a vmlinux image lying
around (vmlinuz, yes, compiled with bzImage option).

TIA.

ksymoops 2.3.4 on i686 2.2.14. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.2.14/ (default)
     -m /boot/System.map-2.2.14 (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.
