Hello,

I have an Intel Apollo Lake NUC6CAYH where I run Kodi v17 and also v18 on
Ubuntu to watch DVB-T2. For decoding the HEVC streams I use vaapi.

When I switch channels I get an GPU hang with a 50% chance. I experienced that
hang with Debian Sid, OpenELEC and also Ubuntu. Upgrading to 4.14.2 mainline
Ubuntu kernel did not help either.

Could you please take a look or suggest a work-around?

Thanks,
Gregor
