I'm having the same issue installing 10.04 Server on a Supermicro 6013P-T using two identical 500GB Seagate drives. The installation proceeds fine, grub says it installs, and upon reboot I get this mount error:
mount: mounting /dev/disk/by-uuid/<uuid> on /root/ failed: Invalid argument

The UUID for md0 doesn't exist in /dev/disk/by-uuid in the initramfs shell. If I boot off the desktop LiveCD and install mdadm I can do a scan and detect both md0 and md1 (swap), and mount them. md0 is resyncing when I do this. fsck reports no errors on md0. I've spent countless hours on this, very frustrating.
