[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?

Re: [SOLVED] Network interfaces disappeared after upgrading to 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.
