Crash

After resuming from sleep, the desktop becomes unstable showing only the cursor and a black background. It eventually recovers, but remains unstable until reboot. Unstable desktop also occurs after hot plugging HDMI.

Crash dump attached.

i915.enable_execlists=0 on the kernel commandline I think should resolve this.

This does appear to have fixed my resume from sleep issue, but there's still instability after hot plugging HDMI. I'm not sure it's related though.

Please add a new report for the HDMI issue, start with a drm.debug=6 dmesg for the hotplug and describe what type of instability you mean.
