- Boot to usb
- Mount your root filesystem
arch-chrootyour mounted root filesystem- mount
/boot mkinitcpio -p linux
Steps 1,2 and 3 are the entry way to solve all “unbootable Arch” problems by the way, presuming you know what needs to be changed to fix it of course.

For a while, I had to do this after every kernel update
Turns out, i accidentally had two /boot folders. One was is own partition, and the other was on the rootfs partition. When Arch booted, the separate partition was mounted over the rootfs /boot dir, “shadowing” it
Except, UEFI / GRUB was still pointing to the rootfs partition. So when pacman installed a kernel update, it wasn’t able to update the kernel that UEFI was booting, but it was able to update the kernel modules
Kernel no likey when kernel modules are newer than the kernel itself
