Description Peter Barth 2013-03-13 21:40:29 UTC

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?

Try using non kde desktop for a while (gnome, xfce, ...) and see if you have same issue.

Comment 2 Peter Barth 2013-04-24 21:00:53 UTC

I'm running xfce for >3 weeks now without a problem. 

On a side note I'm still using most KDE apps I'm used to (konsole, konversation, akregator,...).

Comment 3 Marek Olšák 2014-01-23 14:10:25 UTC

It might be a memory link in KDE. Is this still an issue with the latest KDE and the latest Radeon driver components?

Comment 4 Peter Barth 2014-01-23 18:18:59 UTC

Currently running radeon driver 7.2.0, xorg-server 1.14.3 and kde 4.11.2 with no problem. So this bug can be closed.

However, I want to note that the memory wasn't freed even after shutting down kde,X,kdm,...
