Yes, I am seeing this too.

I believe the initrd is broken, or rather the /sbin/mkinitrd shell
script that generates /boot/initrd-xxxx is broken.

here is what I mean

I see two trees of kernel modules for both the -default and -xen
kernels and it appears that the init shell script is loading up the
modules for the wrong kernel (i.e -xen kernel, -default modules !)

I don't know how to fix mkinitrd, but I am going to try to fix up
the initrd image by hand. delete the extraneous modules and edit
the init script to load just the -xen modules.

I'll reply when I find out if this helps or not.
