After suspend/resume the gpu hang for 20 seconds with [ 109.349028] [drm] stuck on render ring [ 109.349397] [drm] GPU HANG: ecode 7:0:0x85fffff8, in kwin [1667], reason: Ring hung, action: reset The hang only happen with the new 4.4-rc1 kernel, never with the 4.3 stable, but even with the 4.3 kernel there is the *ERROR* mismatch in has_drrs in dmesg.

About the only big nearby change was PIN_HIGH. You can try reverting commit 101b506a7fc7be3f0d0a337ade270eb5eb5a2857 Author: Michel Thierry <michel.thierry@intel.com> Date: Thu Oct 1 13:33:57 2015 +0100 drm/i915: Wa32bitGeneralStateOffset & Wa32bitInstructionBaseOffset and see if that makes the hang go away, otherwise I'm out of good guesses and a bisection would be most invaluable.

Yes, reverting that commit fix the hang. Thank you
Hi The bug is still present in 4.4-rc2
Hi Just tested the 4.4-rc3 , the bug is still present
In the 4.4-rc4 the dmesg error (has_drrs) is fixed but the gpu hang is still there.
Hi The bug is still present in the 4.4-rc5 kernel. Attached is a new gpu crash dump from this kernel.

Hi Just tested 4.4-rc6 , no changes. I purged the oibaf ppa, revert to mesa 10.1 stable with no luck, just to check that the problem is not in mesa. But reverting drm/i915: Wa32bitGeneralStateOffset & Wa32bitInstructionBaseOffset still fix the hang. Once i noticed after gpu hang in dmesg (i don't know if it is important): [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe C I also find that switching VT with CTRL ALT F1 is not working since 4.4-rc1, i just have a black screen with nothing displayed on it, but typing something (in the dark sudo reboot) is working. But i suppose that this is a separate issue.
Hi Happy new year and my best wishes for all the intel team. The bug is no more present since the 4.4-rc7 kernel. I didn't experience a single crash the past 7 days. I just started with the 4.4-rc8 kernel, no crash for now.
I have the same issue in both 4.4-rc7 and 4.4-rc8
Same problem here. Kernel -- release 4.4 Graphics: Card: Intel Haswell-ULT Integrated Graphics Controller Display Server: X.org 1.17.4 driver: intel tty size: 142x35 Advanced Data: N/A for root When I receive a gpu hang, X shows up slower than usual and ttys break.

Hi Just to say that for me the problem is fixed since the 4.4-rc7 kernel. I have no more a gpu crash for more than 3 week's now (ivybridge graphics). I opened a separate bug report for the tty problem here . https://bugs.freedesktop.org/show_bug.cgi?id=93483

Timeout. Assuming that it is fixed by now. If this is not the case, please re-test with latest kernel & Mesa (12-13) to see if this issue is still occurring since there were improvements pushed in kernel and Mesa that will benefit to your system.
