Still did not work. Bisect or are there some other things to try? I tried bisecting without much luck. It started with about 4000 commits to check. It was still bad when it reached the first 1000 commits post .37. Then all boots started crashing. I think its possible to restrict a bisect to a directory - if so, what dir should I try?
