dmesg 4.9-rc1

Happens with 4.8 and 4.9-rc1. I haven't tried 4.7.

This pipeline hangs the GPU very quickly:

gst-launch-1.0 ximagesrc display-name=:0 use-damage=0 startx=0 starty=0
endx=1919 endy=1079 ! videoconvert ! video/x-raw,framerate=60/1,format=NV12 !
vaapih264enc ! h264parse ! matroskamux ! filesink location=output.avi

attached dmesg is from 4.9-rc1.

As far as I can see, it also produces one frame corrupted output with the image
being duplicated vertically and then squashed to fit into 1920x1080, see bug
98278.

Probably not related to <a class="bz_bug_link
