I have a pi-stomp 3 and the System Shutdown option only shows the red "pi Stomp!" screen and does not actually shut down the machine. If I unplug the machine when it's on that screen it only reboots to a white screen and I have to reformat the card to get it running again. ssh pistomp@pistomp.local does not work. I even tried plugging it into ethernet with no success.
I expect that this is not the intended behavior, but I don't know the proper way to turn the device off for transportation.
