it only show 0xc8 if i have the wrong baudrate, otherwise nothing is shown on picocom's output. when i plug the poe hat, which has a fan (loaded by an overlay) it turns on, which would mean that it was loaded, right? but, i get no serial/hdmi output, no network uplink and only the green led is on. the same setup on another board works

I'm getting the exact same error after upgrading from kernel 6.12.58-current-rockchip64 to 6.18.10-current-rockchip64 on one of my NanoPi R4S. After a reboot, the network interface enp1s0 is missing. After shutting down and restarting, it reappears. If I revert to kernel 6.12.58-current-rockchip64 using armbian-config, the enp1s0 interface is also present after a reboot. Are there any suggestions on how I can resolve this issue without remaining on kernel 6.12.58-current-rockchip64?

elaborate. If there is only garbage output your usb uart adapter may not be able to handle this speed. Example would be CP2102 which outputs garbage instead of gracefully failing when "overclocked".
