https://bugzilla.kernel.org/show_bug.cgi?id=71891 --- Comment #5 from sdh <sh.siddhartha@xxxxxxxxx> --- Finally got around to doing this. And the result: ec5891fbe1b078b191b25a13a2cc40b58fb7a693 is the first bad commit commit ec5891fbe1b078b191b25a13a2cc40b58fb7a693 Author: Christian König <deathsimple@xxxxxxxxxxx> Date: Mon Apr 8 12:41:36 2013 +0200 drm/radeon: init UVD clocks to sane defaults Just until we get proper DPM for that.

From 3.13 onwards, this is always triggered. But that may only be due to config changes in the Arch installer. This is a one line edit, which later was shifted to a different function. Is enough to resolve the bug (which is still present in the latest kernel tested until v3.14-7247-gcd6362b).
