--- Comment #11 from madcatx@atlas.cz --- I tried to revert my git repo to 3.12-rc2 tag to see if I could do another round of bisecting but it turns out that even 3.12-rc2 was broken. I don't know I missed that. It seems that the previously pinpointed commit is the cause. Unfortunately the commit won't revert cleanly no matter what I try...
