Please post as much information about your hardware configuration as you can; please also see my recent posts to -mobile for descriptions of how to pull a backtrace in the situation where your machine faults and drops into the debugger without the ability to 'call doadump'. I now strongly suspect we have a bug in ata(4). I will backtrack through green_at_'s recent commits concerning atapicam as I think this may tell part of the story (he identified some other issues and suggested fixes, I have a hunch he is on a similar track). I'm in a debugging session now and will post further results of my findings on -mobile. Regards, BMS
