I think the above error is somehow related to me using LVM. I tried to upgrade my GRUB to GRUB2 to see if this would resolve the above error messages in post #2. Using Karmic Beta, I followed the directions of https://wiki.ubuntu.com/KernelTeam/Grub2Testing and my computer would not reboot. I've now abandoned LVM since from reading online, it doesn't seem to be well supported yet, e.g. Ubuntu Live CD.
