I can reproduce the problem! If I watch youtube for short amount of time the graphics will freeze with the following kernel messages:

I'm not sure why it happened this morning at 7am. My only guess is that a janitor came in and touched the mouse which woke the screen up after a couple of weeks of sleep. (I have been using the machine remotely for computations, which had finished yesterday, but the building was closed so I'm guessing this is the first time the screen has come on in a while). The first unusual entries in my kern.log are: Aug 20 07:02:43 winters kernel: [2218007.668454] radeon 0000:03:00.0: ring 0 stalled for more than 10248msec Aug 20 07:02:43 winters kernel: [2218007.668465] radeon 0000:03:00.0: GPU lockup (current fence id 0x00000000000799d4 last fence id 0x00000000000799d6 on ring 0) They are plentiful, and are mixed with other messages (see attached log file) such as: Aug 20 07:03:00 winters kernel: [2218025.438173] radeon 0000:03:00.0: failed VCE resume (-110).
