          Priority: medium
            Bug ID: 62311
          Assignee: dri-devel at lists.freedesktop.org
           Summary: (kernel) memory leak
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: fdo at won2.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

I'm experiencing a (kernel) memory leak for several months now and it seems to
got worse. I found a bug on
https://bugzilla.kernel.org/show_bug.cgi?id=43751#c11 but no solution yet
(disregard command 12, it's not true ;)). I asked on IRC #fdo and #radeon and
got told to file a bug here on fdo.

At some point I always run out of main memory and got lots of kernel messages
like those:
[drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object (4096, 6,
4096, -12)
[TTM] Out of kernel memory
[TTM] Out of kernel memory
Repeating over and over again. I'm currently running radeon driver 7.1.0, mesa
9.0.1, xorg-server 1.13.1, KDE 4.9.5 (tried with compositing enabled and
disabled).

I don't know what to do or how to debug this, could anybody please help?
