          Priority: medium
            Bug ID: 69738
          Assignee: wayland-bugs at lists.freedesktop.org
           Summary: [bug] gst-vaapi playback no longer functional in
                    v1.2.91
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: joe.konno at linux.intel.com
          Hardware: All
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

gst-vaapi playback under Wayland/Weston 1.2.91 is no longer functional.
Playback can occur for seconds, but then hangs on a frame. At that point, dmesg
reports "*ERROR* stuck on render ring". From that point on, the display becomes
unresponsive and system becomes highly volatile, requiring a hard power-down of
the unit (soft reboot and soft shutdown inoperative).

#To Reproduce

  1. Launch Weston
    weston-launch -- -i0

  2. Play a hardware-accelerated video through VA-API
    gst-launch-1.0 filesrc \
      location=$HOME/Videos/big_buck_bunny_1080p_h264.mp4 ! \
      qtdemux ! \
      vaapidecode ! \
      vaapisink fullscreen=true

#Expected Result

Video plays from beginning to end smoothly without issue.

#Actual Result

Video hangs seconds after playback begins, and enters an unrecoverable error
state.

dmesg emits:
[drm:i915_hangcheck_elapsed] *ERROR* stuck on render ring

Display hangs on last displayed frame. VT-switching, input devices, and display
in general unresponsive and useless. `shutdown` commands issued over ssh appear
inoperative.

Only known recovery method is to power down the hardware.

#Workaround

Append kernel boot parameter: i915.i915_enable_rc6=0

This kernel boot parameter allows playback to continue, though it is not a
permanent solution.

#Configuration

  Hardware: "Sandybridge" era CPU with integrated graphics, Celeron SKU
  OS: Fedora 19 64-bit
  Kernel: 3.11.1-200.fc19
