[SOLVED] Network interfaces disappeared after upgrading to new kernel

After upgrading linux kernel from 6.2.11 to 6.3.1 and rebooting my system all network interfaces were gone, all I see in the output of the `ip link show` is the loopback device.

My setup is pretty simple, I'm currently using systemd.networkd and wired Ethernet connection, I've tried switching to NetworkManager, but that didn't help.

Debugging performed:
* No errors in the dmesg log
* systemd.networkd is running

Downgrading the kernel to 6.2.11 from the cache fixes the problem for now:
sudo pacman -U /var/cache/pacman/pkg/linux-6.2.11.arch1-1-x86_64.pkg.tar.zst

Any advice on how to debug this further or maybe I'm missing some new configuration steps required for the new kernel?

I've figured it out, looks like my issue was the same as in https://bbs.archlinux.org/viewtopic.php?id=285345
Namely missing record in the fstab for /boot partition and had nothing to do with specific kernel verison, rather with kernel update process in principle. Adding the entry/updating/rebooting helped resolve the problem.
