--- Comment #4 from madcatx@atlas.cz --- Bisecting of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git revealed that the first bad commit is "bbd34fcdd1b201e996235731a7c98fd5197d9e51". I was getting hard freezes from which the only escape was a hard reset during bisecting, see the attached image for the error message.
