Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed.

Try using armbian-config for switching kernels

mainline support for rk3588 is still to be considered experimental and problems are to be expected. This is bleeding edge. If you want a mostly stable system use legacy 5.10.y

Most likely, yes. apt update/upgrade will do. Keep in mind though for once 6.7 is still rc and for the other mainline rk3588 support is still to be considered experimental. Therefore problems are to be expected. No support though since this is bleeding edge.

board?

Without full logs debugging is somewhere between hard and impossible.

Can you boot from microSD? Also https://www.youtube.com/watch?v=UpVMO7gbnYM

Check here: https://github.com/armbian/build/tree/main/config/desktop However even if not you can install any upstream package via apt.

Both is possible using the build framework https://docs.armbian.com/Developer-Guide_Build-Preparation/ Check for the "kernel-patch" switch https://docs.armbian.com/Developer-Guide_Build-Options/

Use the build framework to create your own kernel package or even whole new image: https://docs.armbian.com/Developer-Guide_Build-Preparation/ Also if enabling these modules as modules solves this for your feel free to send PR to enable them by default https://github.com/armbian/build/tree/main/config/kernel

That is "heartbeat" behavior. Put some load to it and you will notice the blinking gets faster Can also be adjusted via "trigger" files in /sys. Do something noob'ish like "du -a /sys|grep led|grep trigger" and you will find them.
