I have tried to reproduce this problem with the latest git (torvalds/linux.git) and also went back to Linux 3.11 and I still got the hang with both, my plan was to run git bisect, but the problem still occurs. I opened this bug in bugzilla if it's preferred to deal with the problem there: https://bugzilla.kernel.org/show_bug.cgi?id=112351 Thanks, Diego
