Brian:

The next time this happens, you'll need to grab a back trace from the
kernel using kdb.

You'll see the kernel go to a gdb style prompt, just type "bt".

That will help determine what prompted that error.

A serial console and/or serial console boot blocks are really useful in
this situation.
