--- Comment #29 from Carsten Mattner <carstenmattner at gmail.com> ---
4.9 has been the most stable DRM stack, since 4.4.92 can also be made to
hang the GPU with the workload, as I noticed running it for hours today.
Haven't seen a single hang with 4.9 yet. Too bad 4.4 will be Extended-LTS
while 4.9 will be EOL soon. The concurrent use of VAAPI seems to trip
up things eventually with kernels <4.9 and >4.9 but not 4.9.
