            Bug ID: 90851
           Summary: nine and skyrim: unable to handle kernel paging
                    request
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.19-rc2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: haagch.christoph@googlemail.com
        Regression: No

full dmesg

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.

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] (rev ff)

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?

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.

--- 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.

That's ENOMEM, so it looks like the kernel runs out of memory. Maybe a leak
somewhere.

> But I am relatively sure that it did not happen with 3.18.

Can you bisect?

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.
