On my Carrizo with the tip of drm-next as of today I get VM faults near the end of the piglit tests (with "-x max.*size") which then manifest UVD problems when decoding with a system suspend in the middle. Attached is the dmesg log. Suspend works fine if I don't trigger the VM faults first. I'll see if I can bisect down the VM faults since I think this is a relatively new regression (with max.*size excluded).
