It's a bit strange that the messages do not include any information on
the address where NULL pointer dereference takes place, without it
it's pretty hard to tell what happens. If you are able to return to
the PROM 'ok' prompt after these messages, you can try to get a stack
trace using 'ctrace' and register dump using '.registers' commands. If
they are reproducible from one crash to another, then we should be
able to track down the location of the crash using it.
