           Product: DRI

          Priority: medium

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 bug 97240, but maybe?
