Playing with PRIME on 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff)
mesa git, llvm svn with si scheduler patch from axel davy, but I'm pretty sure I have seen the exact same thing with pure mainline too.
It takes a while of gameplay to provoke, 20-60 minutes or so.

--- Comment #1 from Christoph Haag haagch.christoph@googlemail.com --- Created attachment 187601 --> https://bugzilla.kernel.org/attachment.cgi?id=187601&action=edit same with 4.1 lqx
Indeed. This one is from linux 4.1 with mainline mesa git and mainline llvm 247518.

--- Comment #2 from Christoph Haag haagch.christoph@googlemail.com --- Created attachment 197781 --> https://bugzilla.kernel.org/attachment.cgi?id=197781&action=edit dmesg from 4.4-rc5
The call trace looks a bit different with linux 4.4-rc5.
There are also copious amounts of intel and btrfs issues, relevant radeon issue starts at line 2876.

--- Comment #3 from Christoph Haag haagch.christoph@googlemail.com --- On second thought, this one might have been caused by the intel hang.

--- 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.

--- Comment #5 from Christoph Haag haagch.christoph@googlemail.com --- It's annoying because after this happens the GPU doesn't power off with runpm anymore and requires a reboot.

--- Comment #6 from Michel Dänzer michel@daenzer.net --- This is the same as bug 96721, isn't it?
https://bugs.freedesktop.org/show_bug.cgi?id=92258 might be related.

--- Comment #7 from Christoph Haag haagch.christoph@googlemail.com --- Created attachment 219231 --> https://bugzilla.kernel.org/attachment.cgi?id=219231&action=edit dmesg with gpufault R600_DEBUG=nodma
I can not confirm it 100%, but I think R600_DEBUG=nodma helps.
So far the unable to handle kernel paging request did not happen with R600_DEBUG=nodma. I only got a GPU fault (playing csgo with nine), maybe unrelated, dmesg attached.

False alarm, I just got
