So you can get all sorts of different callers causing the same warning, we just have to look at the backtrace to get a hint of who is causing the problem. Is there any way to break this one down further by caller so we can try to narrow it down? I thought you did that for other types of warnings in the past (may_sleep(), etc.) thanks, greg k-h
