D. R.,

  I just stumbled across the information in the mkinitcpio wiki page working a
'dm'raid boot failure. Take a look at:



Using RAID

First, add the mdadm hook to the HOOKS array and any required RAID modules to
the MODULES array in /etc/mkinitcpio.conf.

Kernel Parameters: Using the mdadm hook, you no longer need to configure your
RAID array in the GRUB parameters. The mdadm hook will either use your
/etc/mdadm.conf file or automatically detect the array(s) during the init phase
of boot.

Assembly via udev is also possible using the mdadm_udev hook. Upstream prefers
this method of assembly. /etc/mdadm.conf will still be read for purposes of
naming the assembled devices if it exists.

  HTH, sorry if you already had the info.
