The guide worked great and deployed successfully. However, I am seeing an issue where power consumption reported by nvidia-smi stays elevated after the transcode streams have ended. Restarting the plex media server service allows the card to return back to normal idle.
Has anyone else experienced this?

It looks as though the GPU’s power state is stuck in P0 and not returning to P8.

EDIT: Nevermind, found the large thread about the documented power states issue.
