Is this a regression? If so, can you bisect?
Narrowed it down to the UVD merge for 3.10 (f18353eee757).
ec5891fbe1b0 ("drm/radeon: UVD bringup v8") was the first commit with the "fence wait failed" errors:

Seven commits in between [f2ba57b5eab8, ef0e6e657cfe] were also bad, but with a different error message:
