Once the initial problem hits, the box more or less grinds to a halt and will eventually kernel panic and reboot. Explicitly trying to reboot the box results in a solidly hung box requiring a hard reset. Anyone have any thoughts, any extra debugging if/when this should happen again that would be useful? - John 'Warthog9' Hawley
