I can confirm @sisyphos experience. After checking power supplies and SD cards doing apt-get update and apt-get upgrade the armbian image continued to crash frequently and fail to boot doing many reboots to get to a login. But the Debian 4.4 image he linked to installed and booted to a desktop on it's first attempt.

I'm facing a similar issue on my Banana Pi M64. It runs through reboot in 10 seconds several times before eventually getting me to the login. It did allow me to change the default password but now it reboots any time I get to the login and enter the password.
