Created attachment 98147 [details] /sys/class/drm/card0/error Hi, I'm using Arch Linux. I get this error message sometimes when switching from X to tty(s) or using mplayer (xv). The X is still stable. If I set DRI to False and NoAccel to True in xorg.conf, the message gone. But it's not a solution for me, because of the poor graphic performance. $ dmesg: [drm] GPU crash dump saved to /sys/class/drm/card0/error [21787.534947] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Can you confirm that DRI false fixes this? That would be unexpected from the symptoms at first glance.
Tested and you're right, this not necessary. Only '"NoAccel" "True"' fixed this. The correct xorg.conf: Section "Device" Identifier "card0" Driver "intel" # Option "Dri" "False" Option "NoAccel" "True" EndSection
Is it always the same error for VT switching and Xv? Can you please attach /sys/kernel/debug/dri/0/i915_gem_gtt after the error?

Not always. On the latest attempt to understand the bug, i run mplayer for 4-5 hours. And then my screen was black, responded to nothing, I hit SysRq + REISUB, but it didn't help. Only removing the power cable saved me. This single message remained: [drm] stuck on render ring [drm] GPU crash dump saved to /sys/class/drm/card0/error [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Could you please retest with latest -nightly?
timeout. Feel free to reopen if you are still able to reproduce on recent kernels updating new logs.
