           Summary: [radeonsi,R9 270X] System lockup when using
                    mplayer/mpv with VDPAU
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: custos.mentis at gmail.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

With mesa from today's git repository I am getting hard system lockups while
trying to play a movie with mplayer/mpv configured to use hardware acceleration
(vdpau).

I was able to bisect the commit causing those lockups. The responsible commit
is     1c03a690bfc3265c7fefa7f87e69782a6672a9b2 "radeonsi: use gpu_address from
r600_resource".

There is no related message in the logs, since the lockup is immediate and hard
reset is required.

I use libdrm, glamour, mesa, and xf86-video-ati from today's git with
xorg-server-1.15.0; mpv-0.3.11 with libav-9.14 and libvdpau-0.7.
