I can confirm V4.1.0 Beta release 1 that on reboot(pulling the plug and plugin back in a day later) the OS seems to corrupt and you get a long load time on the admin page, if it loads at all. When it loads it is black and white picture of Beryl with the password box. Will not accept password that was configured. You are able to SSH into it with the password. I Ubooted it back to 3.215.
