Description thomas.hotz 2012-11-18 14:42:03 UTC 
I always get this error when I start up my Thinkpad Edge E530. This error was introduced with kernel 3.6.

[drm:__gen6_gt_force_wake_mt_get] *ERROR* Timed out waiting for forcewake old ack to clear.

Take a look here:
https://bugs.freedesktop.org/show_bug.cgi?id=54521

I'm afraid all 2012 ThinkPads-Models are affected. The developer has told us that this should be harmless. But if that is correct, than *ERROR* is the wrong log level.

Yep, it's a real ERROR but without bad side-effects. Patch is creeping towards mainline ...
