Is it possible that your kernel falls into the debugger ?
You could try to recmpile a kernel without 'options DDB' and see if you
get a core dump ...

When the box looks up, did you have any X activity, or does it also happen
when the display is idle ? Could be that your video board looks up the
PCI bus (I've seen this happen ...).
