Christoph, it seems that you are using the radeon driver and not radeonhd so if you get the same crash it is most likely a bug in the mesa driver which is used in both cases. The warning seen is definitely from mesa, but I am not sure if it is related to the crash.

Can either of you try to get a backtrace (https:/ /wiki.ubuntu. com/DebuggingPr ogramCrash)?
