--- Comment #6 from Tom <neatnoise at gmail.com> ---
I confirm a bug. It occurs when playing h264 encoded videos using hardware
vdpau acceleration. It happens using many players (tested with mpv, vlc),
kernel 4.7, 4.8 and current mesa-git.

glxinfo:

OpenGL renderer string: Gallium 0.4 on AMD BONAIRE (DRM 2.46.0 /
4.8.0-rc8-mainline, LLVM 4.0.0)
OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.1.0-devel
(git-1d466b9)


dmesg messages while playing videos:

[  212.406985] [drm:radeon_uvd_cs_parse [radeon]] *ERROR* Handle 0x3a200001
already in use!
[  212.406999] [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream !
