I can confirm that switching to network-manager seems to make the Bookworm image more stable on my hardware.
@bobby3605 @bundle @Eatocee can you confirm if one of the two options below work for you as well.
Use Debian Trixie image instead of Bookworm. These can be found by scrolling a bit further down on the official download page at https://www.armbian.com/bigtreetech-cb1/
OR switch to NetworkManager
sudo apt install network-manager -y
Change renderer from networkd to NetworkManager in /etc/netplan/10-dhcp-all-interfaces.yaml
Yep, looks like it's about the netplan renderer. I've tried the actual image instead of the one I built locally and even just a reboot is able to reproduce the issue. The main difference is that on the image I built networking was via NetworkManager by default, while the image on the website uses systemd-networkd.
