Thanks for the detailed bug report! The dump you attached indicates a GPU hang. We use pristine graphics stack as supplied by Ubuntu, so that's a bug in Ubuntu. Marking affected.
The dump specifically mentions this: [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. [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. So could you also report this bug to Intel developers at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI ? You might want to attach the auto-generated Dependencies.txt as seen above to that bug report as well.
