I'm not the worlds most experienced user of gdb but I can't see any
evidence of a hardware fault and the processor shows all indications of
running. It seems likely to be looping with memory faults or otherwise
jammed somehow.

Is there anything I can use in /proc to monitor page faults or anything
I can do with gdb to help narrow this down?
