To me, this sounds like the RAID array is being given the wrong name, or the
mdadm hook isn't being added to /etc/mkinitcpio.conf.
When you get the above error message, are you dropped to a busybox shell? If
so, can you do:
# ls /dev/md*
...to see if the array is being started at all?
This should be fixable without going through a full install each time. Just
boot the install disk, insert md_mod, and cat /proc/mdstat to see if your RAID
array is working. If it is, you can chroot into it in the normal way and fix
whatever configuration issue this turns out to be.
