Comment 74 for bug 477104

OK Joe I have got the same issue.

This is an issue with kernel patch 15 magic number

try
 linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda3
loop=/ubuntu/disks/root.disk

instead of

 linux /boot/vmlinuz-2.6.31-15-generic root=/dev/sda3
loop=/ubuntu/disks/root.disk

And don't forget to initrd the xxx-14-xxx.img
