<0>Kernel panic - not syncing: Fatal exception in interrupt

If there's need for further info I'd be happy to provide it. For now
 the box is rebooted into the same kernel and running the same
 PG/eD2k programs, if the issue reproduces I'll follow up on my
 own message.

Any chance you can get the entire Oops including registers etc
using netconsole or serial console?
