Problem description:
Installed the latest stable image on a clean sd, booted up and configured wi-fi. I try to go in the Xbian Settings but it just hangs at 25%.
I connect via ssh and then i do
apt-get update
apt-get upgrade
The device then reboots automatically and on every reboot the display show only the splash screen with "starting xbmc..." and suddently it becames black without showing nothing, after some time it comes back on the text environment


How to reproduce:
Install the stable image with Xbian-Installer on a 4Gb Sd card, configure the embedded wi-fi with the keyboard, connect via ssh and do a apt-get update & apt-get upgrade


FootNote: if i download the latest build of Xbian the file size is just the half of the stable release and when i boot up it just show a login prompt but even if i plug an usb keyboard i cannot log-in. Any other experience the same issue?
FootNote2: to reboot the device i have to type "sudo reboot" two times
