The problem is, in part, that the machine locks up - it doesn't panic.

Hmmm. Can't imagine what it might be hardware-wise - when running crashme 
on a local console, there's no audio, no serial, no ethernet, perhaps a

Any ideas on the best way to output debugging statements that wouldn't 
overwhelm the console?
