--- Comment #6 from Emelianova Svetlana <svetlana.emelianova at intel.com> ---
I built the latest drm kernel from
https://anongit.freedesktop.org/git/drm/drm.git f06ddb5 commit. GPU HANG
appears too. 
I attached sample_encode and bash script which runs it. Need to replace
"(path/to/stream)" to real stream path and replace correct resolution (-w -h)
in script. Stream should be YUV format and has not less 4k resolution. Need to
build mediasdk environment from https://github.com/Intel-Media-SDK/MediaSDK. 
For reproducing it is necessary a multiple launch, I ran with command line:
"./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh &
./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh &
./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh &
./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh & ./catch_GPU_HANG.sh &
./catch_GPU_HANG.sh"
