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

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.
