--- Comment #4 from Christoph Haag haagch.christoph@googlemail.com --- Created attachment 198561 --> https://bugzilla.kernel.org/attachment.cgi?id=198561&action=edit dmesg from 4.4-rc7
But this one from 4.4 rc7 is without intel hang. Yet another different backtrace.
Bonus cpu soft lockups and rcu_sched self-detected stall on CPU.
Display completely froze and normal reboot over ssh didn't work.
