bananapinas got a reaction from Igor in Lime2 mainline kernel with Debian 9 (stretch) becomes unresponsive (forced reboot required)
apt-cache policy shows version 5.35 and 5.31 for uboot and image. image 5.32 has no matching uboot. So I'll try 5.35 first and if it occurs again I'll try 5.31.
But so far your help is really appreciated.
I really like the armbian project and will use it on my raspberries and banana pi (without pro) soon also.
Donation on the way
