GRUB does not assemble raid. That's why it only works with RAID1. By your own account, GRUB has succeeded, therefore GRUB is not the problem. The problem is the kernel The kernel assembles RAID by looking for partitions of with the Linux RAID partition type, finding out what kind of RAID they are, and assembling them (according to their RAID volume UUID). You apparently only have one RAID volume. It's probably being assigned to /dev/md0, yet you are passing root=/dev/md3.. not sure why you are doing that.
