A friend told me that he found out it is a problem in some BIOSes with
UEFI that can not handle a boot of md UEFI partition.
Perhaps it also depends how they handle the raid of a whole disk.
Are you trying to boot from that raid?
Forgot to ask what is in your /etc/mdadm/mdadm.conf and the IDs of the disks
IMO the problem is that if it is not a partition the mdadm can not assemble
as it is looking for a partition, but not sure how grub or whatever handle
it when you boot off the drive.
