My ROCK Pi 4A no longer boots to completion after I upgraded to the latest version of Armbian. This appears to be because the change of kernel from 6.6.63 to 6.12.9 has resulted in anything connected to the NVMe interface to longer be recognized.
I found a post on the Armbian forums from someone with a 3C who was having the same issue, so it appears to be fairly widespread across models.
The good news is that it seems not to be an issue anymore with the 6.13 series of kernels.
