dmesg after the lockup, got switching to a VT
I am using kernel 3.11.0-18.32 (default Ubuntu 13.10 kernel) with mesa from git
on a RV530. The system is usually very stable, however when running
sauerbreaten with wake6 map (sauerbraten-wake6 package on Debian/Ubuntu) this
way:
sauerbraten -lwake6
after some minutes I get the following lockup:
[ 8425.176130] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec

Full dmesg is attached. After the lockup I can switch to/from console, but I
have to reboot because the screen is corrupted/flashing.</pre>
