This looks like one of the many different kinds of messages I got during the boot attempts reported in my posting on bug 29858. I probably got this message when I was trying to boot from the Ubuntu partition under grub and before I decided to copy the Ubuntu kernel and initrd to the /boot partition from my (primary) FC5 installation and try to boot Ubuntu from there.
