No additional strenuous load is running on the compute stick, only this
transcode. We have not modified the standard cstates and the freq scaling
governor is set to "powersave".

shield at tobeprovisioned1804:~$ cat
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
powersave

Please me know if there is some different configuration which is less likely to
exhibit this issue. We previously have put stress-ng loads on the CPUs to
better simulate what we typically would utilize, and that configuration seemed
especially stable... but depending on periodic CPU activity to prevent GPU
hangs is just playing russian roulette with the GPU video encoder.
