Finally got around to doing this. And the result:

ec5891fbe1b078b191b25a13a2cc40b58fb7a693 is the first bad commit

    drm/radeon: init UVD clocks to sane defaults

    Just until we get proper DPM for that.

So this has been present since 3.10, but was triggered only after installing
the radeon driver (xf86-video-ati in Arch Linux). 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).

Thanks
