Description Shawn Starr 2015-12-18 07:58:05 UTC 
Kernel is spamming non-fatal GPU VM faults:

Mesa from git master: 2015-12-11
kernel: 4.4.0-0.rc5.git1.2.fc24.x86_64

Can I use the new debugging in mesa to capture what is causing fault?
Comment 1 Alex Deucher 2015-12-18 15:09:58 UTC 
Is this a regression?  If so, can you bisect?

Comment 4 Nicolai Hähnle 2015-12-19 07:22:49 UTC 
For what it's worth, I cannot reproduce on Tonga with latest Mesa and LLVM master. Can you confirm that you still get faults after LLVM r256072? Your ddebug_dump contains very large shaders, it would not be surprising if this turns out to be a duplicate of bug 93264.
Comment 5 Shawn Starr 2015-12-19 10:38:39 UTC 
Yes, appears to be duplicate, will continue playing game later today but it looked good in glretrace and actual game play no GPU VM faults noted.
