dmesg after lockups

Since upgrading my kernel to 3.8.0-rc3 using openSUSE packages, I reproducably
get GPU lockups when running FlightGear right after the simulation starts.
Takes a couple of minutes with some screen blanking to quit the application
again. Afterwards the system continues running fine. Activating KDE's desktop
effects may produce the same behaviour.

I'm using the following versions:
Mesa-9.1_git20130117-230.1.x86_64
libdrm2-2.4.99_git20130117-1.1.x86_64

X.Org X Server 1.12.3
Release Date: 2012-07-09
[    17.264] X Protocol Version 11, Revision 0
[    17.264] Build Operating System: openSUSE SUSE LINUX
[    17.264] Current Operating System: Linux sphinx 3.8.0-rc3-1-desktop #1 SMP
PREEMPT Thu Jan 10 20:49:22 UTC 2013 (7ce28dd) x86_64
[    17.264] Kernel command line: BOOT_IMAGE=/vmlinuz-3.8.0-rc3-1-desktop

[    17.264] Build Date: 08 January 2013  11:56:04AM


I could do some git bisecting on the kernel or on Mesa if it helps and I'm
fluent in C. Just tell me how I can help fixing this.
