I've got a theory - can you search the /var/log/kern.log* files on
this guest for any Oops messages? Do you recall experiencing a hang
during your kernel upgrade? I'm wondering if there was an oops at the
time you upgraded your kernel package. Also, can you mount your efi
partition and capture the md5sums of the files under
/boot/efi/efi/debian?

If my theory is correct, you may be able to get back up and running by
booting an older kernel (if you have one), running 'elilo', then
booting back into the 2.6.26-11 kernel.
