Might that be a /etc/mdadm/mdadm.conf in the initramfs listing fewer
devices than it should?
I am not sure (because in this case maybe it shouldn't autoassemble the
array at all), but have a look by unpacking your initramfs. If yes,
update it.
Or could that be a controller that shows the disks to the kernel too
late... do you have multiple controllers?
