Indeed, the 0001-drm-amdgpu-uvd6-fix-allocation-size-in-enc-ring-test patch
(attachement 285473) doesn't work.
Apparently I got (un)lucky enough that it survived 30 suspend/resume cycles,
but testing it again, it failed.

On the other hand, the
0001-drm-amdgpu-uvd6-use-0-as-dummy-pointer-in-enc-ring-t patch (attachement
285469) survived 100 cycles.
