Interesting, as I was about to write something very similar about latest xorg under 9.3-STABLE. I have been seeing the same, hangs and hard lockups. I thought it was the card so I replaced it, but the result is the same. I am also using the new console, and I am also using Radeons. This is definetly video related - it never happens using the system remotely, and sometimes it is just the graphics which locks up (I can ssh in and shutdown). Occasionally, the lockup clears itself and the graphics comes back. Very puzzling - it can go for days without a lokcup, then sometimes I will gte several in the space of an afternoon. -pete.
