On saucy, with kernel 3.11.0-2-generic, I sometimes get the same error
message when having Radeon DPM enabled (radeon.dpm=1). Unity desktop
then freezes and after a few seconds, the screen turns black. However, I
can switch to the console and reboot. When leaving DPM disabled
(radeon,dpm=0), I don't run into this problem. In any case, my computer
always boots fine.

This is some hopefully relevant output that I got by 'grep radeon
/var/log/kern.log' (DPM enabled):
