Thanks for the help.

That's essentially what my grub stanza does.  I've run
update-initramfs.  So I don't know what "attention" my initrd needs at
this point.

As I reported - all the code and mdadm.conf are in it.  In the initrd
shell, if I assemble my root raid disk and exit, the boot completes
normally.

This is squeeze - is it possible that the newer kernel has code to
assemble early?

Is there some other "option" or setting which causes it to assemble early?

Also, are you using md version 1.2 raid.
