NanoPi NEO hangs on boot Bookworm 23.5.1
The problem seems to be kernel version 6.1.30; Just writing image file 'Armbian_23.5.1_Nanopineo_bookworm_current_6.1.30_minimal.img' to SD-card gives the following output via serial console:

'Armbian_23.5.2_Nanopineo_bookworm_current_6.1.30_minimal.img' now works as expected.
However, going to nightly again on my existing installation still the same hang with a kernel file named '6.1.30-sunxi' as well.
So I did a brute-force overwrite of the relevant kernel files from the Armbian_23.5.2_Nanopineo_bookworm_current_6.1.30_minimal.img on the existing installation, then the boot succeeds with:
