I think this is very minor bug since only few of us > are having this problem. That puzzles me too. I wonder if it's something specific to a particular driver we use that others don't? Shall we compare kernel configs? Mine's attached. The only things I'm using that might be unusual for hardware + drivers are: - cgd - bce (the special limited dma mapping) While it's a great idea to do the binary date search looking for a culprit change, I suspect you'll hit the big merge as the culprit, and then it would help to have something else to direct the search.
