I elected to go ahead and try the bisection; here are my results: r248493M/248493: OK r248550M/248551: resets on X startup with nvidia.ko r248521M/248521: resets on X startup with nvidia.ko r248507M/248507: OK r248508M/248508: resets on X startup with nvidia.ko r248493M/248493 was my last working point (built yesterday morning). r248550M/248551 was what failed for me this morning. r248521M/248521 was a convenient mid-point between the above two. r248507M/248507 was the next natural test-point. r248508M/248508 was a guess on my part -- I would normally have gone to r248514, but since I had previously noted that r248508 touched some things that nvidia-driver uses, I thought that test might be worthwhile. I am, however, mildly concerned that no one else appears to be reporting similar symptoms (though I have it on good authority that someone is about to test). Peace, david -- David H.
