There is a fundamental problem in getting a decent log to debug a
crashed kernel. Maybe we should take a hint from Solaris. If the
kernel crashes Solaris dumps core to swap and sets a flag. At the next
boot this image is copied to /var/adm/crashdump where it is preserved
for future debugging. Obviously swap needs to be larger than core, but
this is usually the case.
we've got kdump, but it's not usually enabled by default by distros.
