Oh wait, I probably know what this is.

Are you trying to install lilo on your boot partition?

(i.e. "boot = /dev/sda2" in lilo.conf)

You need to use the mbr (boot = /dev/sda, or whatever disk boots)
(or you could install it on your swap partition, or other non-xfs
partition).  XFS needs block 0 on the disk, but if you try to install lilo
there it will overwrite xfs fs structures.
