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.

--- Comment #1 from Fabio Pedretti <fabio.ped@libero.it> ---
After upgrading to Ubuntu 14.04 I cannot reproduce this issue. Note that I was
using current git of mesa/ati/libdrm with both 13.10 and 14.04. What changed
was the kernel and sauerbraten get updated. I also tried with the 13.10 kernel,
but the issue is no more reproducible.

It could be that the updated sauerbraten has a different path that doesn't
trigger this issue. Closing since I cannot reproduce it anymore anyway.

This is still happening with updated sauerbraten. However I cannot find an easy
way to reproduce it.

I suggest using the old sauerbraten to reproduce it.
