I order a new flash because this thread. Thanks. And how do you explain that i haven't get troubles on next ubuntu image?

I've tryed about 10 different variants. Downloading/compiling, desktop/server, with/without package update, freeze/defreeze kernel. In all variant the same result. Yesterday I tried next image debian with desktop. And... it doesn't reboot. I use bad flash, Nokia 8Gb 2cat. I'm waiting the normal flash, and there is no another flash.

I had only one usb flash 16Gb. Synaptic+gparted. But this is no matter. Reboot absolutely clear system is enough to get the bug. With no login. With no change password or add new user.

I've been installed the latest mainline kernel image with desktop for TinkerBoard from here. It work normal, but only before first reboot. After reboot the system didn't start. I try to compile image on my own. But the result exactly the same. System didn't start after reboot, yellow led blink very fast and the heatsink is extremly hot! I think CPU is under heavy load. Now i use the next image. It doesn't have this problem. But have problem with hw acceleration. Information about my system is here. I've trying start the system by three times and the result ander the spoiler.
