00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M]

dpm enabled, runpm disabled.

Software: xorg server 1.14.5, xf86-video-ati git d571d6a, glamor git 71e7168, llvm svn 197173, mesa git 40070e7.

So I'm not sure whether to report this to mesa or the kernel, but I decided for the kernel because it causes some errors there.

Playing skyrim in wine 1.7.8 with mesa git 00faf82 was working fine. mesa git 40070e7 introduced some rendering errors, but the thing here is that after a while the gpu locks up and if I'm lucky it recovers and I simply can not render anything anymore on the radeon gpu and if I'm unlucky I get a hard lockup of the whole machine.

Important parts for people who google this:

Comment 1 Arek Ruśniak 2013-12-14 22:22:59 UTC 
You can try run wine with R600_DEBUG=nohyperz, it should prevent GPU crash.
Comment 2 Christoph Haag 2013-12-14 23:32:15 UTC 
Indeed, it does prevent all of the above. So I guess the new hyperz implementation for radeonsi is buggy for me... Anyway, it would be preferable to only have the application crash and not the driver. :)
Comment 3 Michel Dänzer 2013-12-18 02:23:47 UTC 
Does HyperZ work better with current Mesa Git?
Comment 4 Christoph Haag 2013-12-18 13:52:10 UTC 
I'm not completely sure it's gone, but it's looking good I think. I'll be "testing" it some more later. :)
Comment 5 Christoph Haag 2013-12-19 18:27:17 UTC 
Ok, I'll close this since I have seen nothing like that anymore so I assume it is fixed by mesa.
