Description of problem:
As soon as my monitor goes to sleep, this error occurs and the only way to restore the system to a working state is to hard reset from the button.

I can SSH in to it from another computer, but running 'sudo reboot' or 'sudo systemctl reboot' only serve to shut down SSH and not actually reboot anything.
