Or have you been cc'ed on patches for this? I'm not convinced that the original report wasn't hardware related. We had taken a machine check exception already, which shows that something isn't quite right. MCEs happening under high load are usually a sign of thermal/power problems of some sort. Oleg's comments may still hold true, independant of the report. I've added Venki to the Cc: as he's recently rewritten considerable amounts of the ondemand governor (though the workqueue mechanics are pretty much the same).
