I'll answer that myself, since I just found the solution to my problem after searching for hours.
Turns out the EFI partition needs to be created with --metadata=1.0 instead of --metadata=1.0:
# mdadm --create /dev/md/EFI --level=1 --raid-devices=2 \ --metadata=1.0 /dev/sda1 /dev/sdb1
Boots fine now.
Cheers,
