Mobian won't boot after ton of updates

[diederik]

After going through the output again:
U-Boot menu
1:      Mobian GNU/Linux 6.1-sunxi64
2:      Mobian GNU/Linux 5.15-sunxi64
Just tried option 2, that works

It would be useful to know which EXACT 6.1 kernel you tried it with. 
The very early kernel versions, like 6.1.1, tend to have various bugs. Often around X.Y.7, most obvious bugs have been fixed and things are more likely to work properly.
