Are you using the raid-extra-boot option? If you aren't you probably
want to be - it'll allow the system to boot if one of the boot drives is
dead.
However, this shouldn't be preventing you from mounting root.

This may sound dumb, but are you sure you didn't compile RAID1 as a
module? If you did, you'll need to use an initrd to load the module
before you mount root. Otherwise, you'll need to rebuild the kernel
with the driver included in the kernel.
