Watching a video in Totem under Gnome 3 in X. Screen froze for a few seconds, then unfroze. Caught the following in dmesg:
[46336.090639] [drm] GPU HANG: ecode 6:0:0x85fffffc, in ositorWorkQueue , reason: Hang on rcs0, action: reset
[46336.090642] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[46336.090642] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[46336.090643] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[46336.090643] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

I was rendering something with Kdenlive at the time, but I didn't see any excessive heat or anything.
Hello James, could be that it is the same problem?
From both logs I see that you have the same CPU Gen (SNB). What mesa version do you have?
Also could you provide a bit more info about video? Any video, or resolution of it matters?
Do you have 1 monitor connected/enabled, or two? (laptop + display, for example)?
Only the laptop's built-in screen connected (LVDS), at native resolution (1366x768). I've not tried any other resolution, not have I seen another hangs. I'll try provoking it over the next few days.
