I am not at 100% sure, but AFAIK when you install the kernel mkinitramfs or
update-initramfs would add the modules already used by the kernel at the
moment of creation of the initrd. This could explain a lot.

As I explained before it is not possible to mount the root fs thus pass the
boot process to init/systemd if you don't have the proper driver(s). If the
drivers are included in the initrd it would boot ok, if not you are offered
the limitted shell. So again initrd is needed unless you have the drivers
compiled in the kernel. You can try this .. just remove the initrd line
when you boot
