Hello, today I made an upgrade of my pine64-mainline and failed miserably - my new armbian image won't boot any more.   So I did some more tests with a new more different sd-cards, power supply and the mailine kernel form the download site (https://dl.armbian.com/pine64/Ubuntu_xenial_dev_nightly.7z): Again, the same behaviour, the image doesn't bott any more after "apt update" and "apt upgrade".   Please, could someone help me with this problem? I hope these lockup
