Never mind that question. I've been able to reproduce the problem and the 
cause turns out to be a script error in grub.

You should be able to boot your system by editing the kernel line for grub 
(you can do that from the grub menu) and change

If you do not know what the correct path is, boot the installer in rescue 
mode and check the device for / in /target/etc/fstab.

The following patch for update-grub will fix this problem.
 convert_kernel26 ()
     # skip /dev/mapper/ from conversion
     if ! echo "$1" | grep -q "^/dev/mapper/"; then
         echo "$1" | sed 's%^\(/dev/[^/]*\)/\(.*\)%\1!\2%'
+    else
+        echo "$1"
