Thanks Les, that was very helpful (and I should have thought of it...). But 
then it gets weird again:

I commented out the /dev/md1 line and the system came all the way up to the 
login prompt. Great! I thought. Enter the root password and...

/bin/bash: Permission denied

doh! well of course I have done nothing special to the permissions there or 
anywhere else. I can see all the console boot messages and they all look 

Booted into single user mode, and that works. /bin/bash has normal perms and 
all seems well. What's more, I was able to mount /dev/md1 on /home and it 
didn't complain. Then I un-commented the line in fstab, rebooted and it 
worked all the way up to the login prompt, it now uses all 3 md devices 
happily. But then, "Permission denied" is all I get. Nice system but it makes 
it hard to maintain when even root can't log in.

Could there be some disk error? I have never had so much bizarre behavior from 
one system. Ready to chuck it out the window.

Is there anything else I can try to see what's up?
