ksymoops is specific not only to the kernel configuration, but to the
order of loading modules. ksymoops and oops output is only relevant to
the exact kernel it is from, so although he could run ksymoops from
another kernel, the output would be completely useless (and completely
wrong). The alternative is to set up a serial console and kdb (the
kernel debugger) to get a stack frame from a second machine at the time
of oops (this should work in most cases, supposedly even if the system
locks up). But trying a more recent kernel is the easiest thing to try
next.
