Same problem.
The issue is that the new kernel has a bad magic number.
So it is unloadable.
But return to grub prompt instead of grub boot menu is very unpleasant.
The following sequence save me:
linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1
loop=/ubuntu/disks/root.disk
initrd /boot/in
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 t
