Hi,
I have downloaded and tested the 6.12 kernel Minimal/IOT images and they are not booting.
I downloaded trixie 6.1, booted, then manually installed latest 6.12 with armbian-config and the reboot failed.
I re-flashed sd card with 6.1, installed edge 6.16.4 (latest) with armbian-config and it booted fine.
