Adding /boot partition to machine breaks deployment

I have a OL8 deployment on MAAS 3.4

when I create a regular deployment with my partitions and only a /boot/efi partition, everything boots up and works as intended. When re-deploying and adding /boot, grub is giving me the option to boot into OL8 but cant find the kernel. when using installation media to chroot into the system, only some of the lvm partitions are active
