GPU Hang/crash on Thinkpad X1 Carbon with an Intel i7-5600U I got the following message: [11136.674235] [drm] stuck on render ring [11136.674985] [drm] GPU HANG: ecode 8:0:0xfffffffe, in Xorg [960], reason: Ring hung, action: reset [11136.674987] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Is any other information needed from me?
Can you please compress the error state and attach it? At a rough guess this is on one of the TLB hangs and you should update your kernel.
Created attachment 114892 [details] error file from previously mentioned error I'll upgrade to RC6 and see if it happens again.
Created attachment 115009 [details] another dump file It looks like the issue has happened again: [ 2768.504078] [drm] stuck on render ring [ 2768.506913] [drm] GPU HANG: ecode 8:0:0xfffffffe, in Xorg [931], reason: Ring hung, action: reset [ 2768.506914] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Oh, execlist vs suspend? Can you please try i915.enable_execlists=0?
setting i915.enable_execlists=0 changed the output, now i get this: [ 308.629021] [drm:stop_ring [i915]] *ERROR* render ring : timed out trying to stop ring I should note, that besides these error messages I don't see any other effects of this bug.
