/var/log/messages from radeon 0000:00:01.0: ring 0 stalled to reboot.

I was away from the computer when the radeon dri driver crashed; I left a fair
number of firefox windows on/tab, some of them may have videos (from BBC news
web site) and animated gifs from another web site on; but it crashed about 5-10
minutes after I was away and I was aware of it because the laptop blipped.
