As the root filesystems is never unmounted, there are still buffers active when the md devices finally gets turned off and invalidates all of its buffers. It sounds like your machine is getting switched off too quickly after the raid shuts down and your IDE drives which has said that the data is safe, haven't actually had a chance to flush it out of cache yet. Can you compile without APM support so that it doesn't actually power down itself?
