This is likely an error with Grub (especially if you switched to Grub2)
or the initramfs image. The use of /dev/mapper indicates you need the
dmsetup package. Boot it using a recovery/live CD, and install all the
"booting from funny stuff" packages:
apt-get install lvm2 evms dmsetup
These will rebuild the initramfs images to include support for a bunch
of special boot configurations.
I'm sorry I don't have better news for you.
