It does not happen very often, but when it does, the game freezes and has to be killed. radeon takes a little wile, but recovers.

mesa was a then recent git master build with master from https://github.com/iXit/Mesa-3D.git merged into it so there's a possibility it doesn't happen with pure upstream mesa.
I think it has only happened in skyrim with nine so far.

--- Comment #1 from Michel Dänzer michel@daenzer.net --- Can you try decoding the backtrace with scripts/decode_stacktrace.sh from the kernel tree?
Does it only happen with a 3.19 kernel, or also with older ones?
https://bugzilla.kernel.org/show_bug.cgi?id=90851
--- Comment #2 from Christoph Haag haagch.christoph@googlemail.com --- I'll have to build a kernel with symbols later and replicate it. It sometimes takes even a few hours of gameplay to have this happen, so it could take some time.
But I am relatively sure that it did not happen with 3.18.
https://bugzilla.kernel.org/show_bug.cgi?id=90851
--- Comment #3 from Christoph Haag haagch.christoph@googlemail.com --- Hm, interesting. I compiled 3.19-rc4 with debug symbols.
I'm also testing Tom Stellard's VGPR register spilling llvm and mesa branches.
After a while of playing skyrim I got the familiar hang where skyrim just freezes, but I did NOT get "BUG: unable to handle kernel paging request" in the system log.
Instead I got this in the terminal from which I started skyrim:
radeon: mmap failed, errno: 12 radeon: mmap failed, errno: 12 radeon: mmap failed, errno: 12 radeon: mmap failed, errno: 12
I'm not very good with the wine debugger... Attaching to the TESV.exe process and then getting a backtrace shows:
Wine-dbg>bt Backtrace: =>0 0xf7702bee __kernel_vsyscall+0xe() in [vdso].so (0x7eada510) 1 0xf7514e02 __lll_lock_wait+0x21() in libpthread.so.0 (0x7eada510) 2 0xf750f5ae __GI___pthread_mutex_lock+0x8d() in libpthread.so.0 (0x7eada510) 3 0xed73ba1d in d3dadapter9.so.1 (+0x128a1c) (0x7eada510) 4 0x0069df9c in tesv (+0x29df9b) (0x7eada510) 5 0xfff0e400 (0x526077e9)
I would try to find out where exactly in d3dadapter9.so.1 this happens but I don't get how to properly attach winedbg --gdb and addr2linux didn't give a line with code, so I probably used it wrong.

--- Comment #4 from Michel Dänzer michel@daenzer.net --- (In reply to Christoph Haag from comment #3)
radeon: mmap failed, errno: 12
That's ENOMEM, so it looks like the kernel runs out of memory. Maybe a leak somewhere.
(In reply to Christoph Haag from comment #2)
But I am relatively sure that it did not happen with 3.18.
Can you bisect?

--- Comment #5 from Christoph Haag haagch.christoph@googlemail.com --- I didn't answer for a while because I didn't have too much time, but also because it hasn't happened anymore. I think it has meanwhile been fixed, wherever the problem was.
