Bug 73619

Please attach your xorg log and dmesg output.  Any chance you could bisect?

Bisecting is quite tricky, I have so far only used the binary kernel packages. 
I can try, however it will probably take a long time until I find something useful if at all. I am not sure when I can call a version good because sometimes the system can run fine for multiple hours and only then start having these freezes.
I currently don't have the time to bisect, so I was hoping there would be some kernel parameters to increase verbosity.

Would running a debug kernel be of any use?

I have now upgraded to Mesa 10.0.2 and it is MUCH better. Freeze only happens very rarely now. Maybe some unrelated change made a race condition that causes this very unlikely. Sadly still don't have the time to bisect the kernel.

I recently had another freeze and was able to attach gdb via ssh, this is the backtrace I got:

Looks like it is somehow freezing when calling the DRM_RADEON_GEM_CREATE ioctl, but maybe gdb attaching causes the freeze to end and this is just afterwards.
Hope it is of some use.

Does the freeze happens also with the stock openSUSE mesa (9.2.2)?
