It usually means either the device is busy at the time the raid startup
happened, or the device wasn't created by udev yet at the time the
startup happened. It it failing to start the array properly in the
initrd or is this happening after you've switched to the rootfs and are
running the startup scripts?

Whole disk raid devices == bad. Lots of stuff can go wrong with that
setup.
