var log message, another crash, 4 days later.

same description as last, from stalled to reboot. This time it happened when I
was running mplayer - with -vo xv, I think. (in addition to firefox).

>From now on I am using some additional patches from look at 3.16.3..3.17-rc7 -
basically anything that affects gpu/radeon and which would apply cleanly to
3.16.3, besides the sleep patch.

The sdma one might be relevant? Also the counter one - the ring test failed on
ring 1 and 3?
