Same issue here:

Also Nvidia 8600, on HP dv9700 laptop:

01:00.0 VGA compatible controller: NVIDIA Corporation G86 [GeForce 8600M GS]
(rev a1)

The same problem easily reproduced by running easytag (GTK app) under KDE.
Using Ubuntu 12.10, kernel 3.5.0.

There were no such issue with Ubuntu 12.04 (kernel 3.2.0).

more info if needed.

I have the same problem with ati card (Radeon HD 6670):

...
[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
[drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object (4096, 6,
4096, -12)
...

This happened with 3.5.x, 3.6.x and currently with 3.7.6. Last known good state
is kernel 3.2.13.

At some point the OOM-Killer kicks in, however, that does not help. I can kill
any app, stop X and my displaymanager, stop mostly any service there is and
that does not help.

/proc/meminfo shows (and that gets worse):
MemTotal:       32880920 kB
MemFree:          729688 kB
Buffers:             728 kB
Cached:         25403768 kB
SwapCached:            0 kB
Active:          3202980 kB
Inactive:       25110208 kB
Active(anon):    3178992 kB
Inactive(anon): 25065012 kB
Active(file):      23988 kB
Inactive(file):    45196 kB
...

sync ; echo 3 > /proc/sys/vm/drop_caches does not help. The memory is gone and
at some point I have to restart to regain memory.

If that helps, userspace is: xf86-video-ati 7.0.0, mesa 9.0.1, xorg-server
1.13.1

Seems to be fixed for me with 3.8.0. No kernel-crash/reboot for 3 days, yay!

I'm running kernel 3.8.7 and still having this issue.  dmesg is full of these
lines:

[126466.384749] [TTM] Out of kernel memory
[126466.384752] [drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM
object (4096, 6, 4096, -12)

This problem started after updating Kubuntu 12.10 a few days ago.  Latest
kernel does not fix the issue.

This is a kwin bug, kwin select msaa visual which is problematic, there is also
a fix in mesa git. In no case this is a kernel bug

I'll give mesa git a try and hope to be able to switch back to kwin soon.
However, shouldn't the memory be freed after killing kwin and after shutting
down xdm and so on? But that's not the case, the error resides.
