The kernel can not use UUID (file system identifier) to find the root partition
If your hard drive has a GPT partition table, the kernel can use PARTUUID to find the root partition, the kernel option format is root=PARTUUID=value found from running example: | Quote: | /dev/sdc1: LABEL="OCZ128" UUID="f7bd2bec-3688-4336-8c63-e6921ae5e3bf" TYPE="reiserfs" PARTLABEL="OCZ128" PARTUUID="89bc9633-fbc9-4a90-8a67-e058cb655d95" Do not include quotes from blkid in the kernel option.
If GRUB2 is involved suggest manual edit of grub.cfg |

DONAHUE,
That works with MSDOS Partition tables too.
I rather suspect the OP is using grub2 and its a grub issue.

That is you /etc/default/grub (a configuration file that gives some default options to GRUB2).
Can you please paste the contents of /boot/grub/grub.cfg; as well as the output of `blkid`? |
