Hi, just to inform that I ran into the same issue as @waddon1 (WiFi no longer works) with the khadas vim-3.
Apparently /boot partition (on the nvme drive) was not mounted when the upgrade took place, what I did was to first fix the fstab as described by @Strit in the post, and since I didn’t have network, pacman -Syu linux was not possible. So I mounted the /boot partition in /mnt/boot, then copy everything from /boot directory into the /boot partition (mounted in /mnt), rebooted and all good…
Thanks for the everything!
