Transcoding problem

My system is Ubuntu 18.04 running on Pentium J45 Apollo Lake mini-PC kernel 4.18. Emby is 4.2.1.0.

 

Harware transcoding works but not consistently with 1080 HEVC 10 bit encoded files.

 

Some files play well and some don't and crash the machine leaving a log like this:

Stopping in mid sentence. But if I play a good file first and then one of the files that crashes the system it then works. Strange I know but the way it is I can't let my famly use the system unless I am around to restart it if it crashes.

 

Any suggestions to troubleshoot this?

 

Thanks, John

Thanks for the speedy reply - I've followed the guides and things work pretty well except after a reboot when certain files don't play and crash the device. After I play a file that I know works first time all is fine - I can restart Emby and the file that crashed the device now works. I've attached some logs from the last induced crash.
