As previous reported by me I had sometimes problems of my machine locking up probably by the driver. This morning I experienced the same type of crash and had a tail -f /var/log/messages running and saw the following appear: Jan 17 06:54:37 garfield kernel: mantis start feed & dma Jan 17 06:54:47 garfield kernel: BUG: soft lockup detected on CPU#0!

I wil try to get some more logging tonight.
