Arduino Yun continuous reset

Default Arduino Yun behavior is to wait for WiFi interface to work.
If you disable Wireless interface (maybe if you want to use it as a simple Arduino with Ethernet features), its startup system will run a command called “wifi-live-or-reset” and your arduino will auto-reset about every minute.

If you don’t need WiFi feature, just comment out the line in your /etc/rc.local startup file and your Arduino starts working as expected.

If you have already disabled WiFi interface, you have to do it as faster as possible, just before your system reboot.
