Normally if the root is on an lvm volume, /etc/grub.d/10_linux passes the lvm name instead of the UUID to the kernel. Did you originally have this sytem installed on a plain volume and then migrate it to a logical volume? If so, you will need to edit the the grub.cfg in that volume to change it to point to the lvm name and then re-run update-grub to pick up the change into your master grub.cfg.
