Observe Linux restart in the APU terminal and RPU application dead in it’s terminal; then both APU and RPU terminals are getting reloaded with the respective subsystems.
Note: As APU is hosting this notebook, the notebook becomes inactive and disconnects during the reboot. After reboot one must reconnect the notebook in the browser. In most cases, after waiting for about 120-150 seconds, just a browser refresh is enough to reconnect the notebook after reboot.
