It look like booting is blocked when the WiFi is unreachable. I had my Edison connected to one WiFi network, and now I'm booting it up and wanting to connect it to another WiFi network. It is currently blocking when it comes to the network configuration for a couple of minutes and the rebooting. Unfortunately I'm about a 2-hour drive from the previous WiFi!
I noticed when I was trying to bring up Debian that the Edison will reboot if it locks up when booting after a couple of minutes, but I don't understand why configuring the network blocks booting.
I should be able to just re-flash the root partition, but we need to figure out why this is blocking.
