dmesg with 3.14.16

Since 3.16.1 am getting this in dmesg and everything gl / video related looks
cpu bound.

[   16.660061] [drm:init_ring_common] *ERROR* render ring initialization failed
ctl 0001f001 (valid? 1) head 000020a0 tail 00000000 start 00193000 [expected

Up to 3.14.16 it works fine but i haven't checked 3.15
