I'll take a shot into the dark: does it work if you add rootdelay=30
to the linux kernel boot line? E.g.

  kernel /boot/vmlinuz ro root=/dev/md0 rootdelay=30

This will incur a 30 second delay during boot. If that makes it
work, you can experiment with lowering this value, but you will need
to have some sort of sleep in there like that, because apparently
your controllers need more time to make the disks available, and
they do not properly convey to the kernel when they're ready.

Cheers,
