Turtlebot minimal.launch not working with Jetson TK1

Hi all

After re-flashing my Jetson TK1 to 21.4, installing ROS and Turtlebot per the wiki, minimal.launch no longer brings up the Turtlebot with the expected chime.

The last few lines I get before the system hangs is

process[turtlebot_laptop_battery-8]: started with pid [13498]
process[capability_server-9]: started with pid [13506]

Looking inside the log file shows:

Previously I was able to run the Turtlebot with the Jetson with no issue even though there was a warning because the Jetson TK1 obviously doesn't have a battery. It looks like now some kind of shutdown signal is being sent when the BAT0 file isn't found. Has anyone experienced this?

Cheers
