Comment 16 for bug 212660

Based on an experiment I ran before I started the git-bisect and found the triggering commit, I would have to suspect the interaction between the new IAA watchdog timer handling in ehci-hcd and the way khubd interacts with the freezer (manually disabling processor 1 after the first failed suspend on my box caused the sched-debug output in include khubd as a runnable process along with pm-suspend).

But that is just a guess, and I don't have enough knowledge in that area to test it effectivly.
