Do you know when they started? My current results are as follows: (all dates relative to GMT-0400) june1: OK june7: OK june10: OK june12: system lockup june14: system lockup june28: gcc ICE, system lockup july22: fault on nofault entry panic aug5: fault on nofault entry panic I have no idea if the lockup problem is orthogonal to the pmap problem or not. Unfortunately, obrien's FBSDID changes thrashed the src tree between june10 and june12 and make getting diffs very painful. For all I know, the lockup was fixed and the pmap problem is new. So I'm thinking about re-starting the search to see if I can find where the lockup changes to a fault on nofault panic. At least this makes things quicker, as the lockups and/or panics happen quickly. If you have any advice, please don't be shy ;) Drew
