CentOS - Apr 2007 - CentOS 5 upgrade from 4.4 fails. Cannot mount /dev/md1 root partition

Have completed two clean installs of CentOS 5 with no issues (other than
permissions on ~/.ssh directory.  One 32 bit system, one 64 bit.  When I
tried an upgrade from 4.4 on 64 bit system with two SATA drives in Raid
1 configuration, anaconda could not mount the root partition /dev/md1.
The error message suggested it was because the partition was not
formated which is obviously not correct.

Any thoughts appreciated. Thanks in advance.

I get the same error that you have when I try to upgrade from centos 4.4
to 5. I haven't tried to a clean install yet. I did try a clean install on
a VMWare machine and it gave me the same error.
