See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=530357
As workaround you can set GRUB_DISABLE_LINUX_UUID=true
in /etc/default/grub and then run update-grub again, so that UUIDs won't
be used for the root= kernel parameter.

Actually this is a bug somewhere in initramfs-tools or somewhere else.
