"set LOGGING=1" in kdb to log the output to disk, via syslog.  But that
only works if the kernel can recover after the oops, if the machine
dies then syslog never gets called.  Your best option is to use a
serial console, Documentation/serial-console.txt, and capture the
serial output on the second machine.

Depends on the type of error.  For a deadlock, bt is useful.  For a
straight oops, it is rarely useful, unless the oops comes from code
that is testing for deadlocks.
