Nothing readly visible, anyway.

Looks as if there is something looping as fast as the clock can push it, and at 
a primitive or 'deep' enough level the tools available can't see it.

Are there any kernel build options aside from GENERIC?

Which kld's in use?

If no clues there, in the absence of panel switches for RUN/HALT/SS, I'd suggest 
building or installing at least a new kernel, if not world.
