Ok Linus and Paul, it took me almost 5 hours to bisect it and the result is: c9b88e9581828bb8bba06c5e7ee8ed1761172b6e is the first bad commit http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c9b88e9581828bb8bba06c5e7ee8ed1761172b6e I hope I didn't get any false positive/negative during bisect.
