I solved the problems with the updates by completely disabling the kernel and firmware updates.. the board is alive and running great with OpenMediaVault .. All unattended updates were disabled completely. I hope the will be a stable kernel for this device in the future. Running it with 6.6.16 kernel which came with the image..

Just like kernel features and drivers such overlays need to be developed to be shipped. So it is very likely that some/most/all overlays for various features are missing. If you need them, vendor kernel is the way to go for now.

Its probably a "feature" of new kernel version that broke some mechanism. Kernel 6.12.y is packed well so its something in the middle, corner case. I also don't know more then you.
