Radeon Acceleration Disabled

[karu.pruun]

It seems not all radeon cards work with GPU acceleration, for instance
I get the following w/o the commit you mention

kernel: error: [drm:pid223:r600_dma_ring_test] *ERROR* radeon: ring 3
test failed (0xCAFEDEAD)
kernel: drm0: error: disabling GPU acceleration

for both Radeon R7 370 and R7 360. I am not sure why the commit was
made, perhaps the cards that generally worked had occasional glitches,
and maybe it's still the case.
