Still no joy.

     I uninstalled:

		kernel-2.6.18-128.1.10.el5.x86_64
		kernel-module-xfs-2.6.18-128.1.10.el5-0.4-2.sl5.x86_64

rebooted into old kernel.  Did following command:

	# yum install kernel-2.6.18-128.1.10.el5.x86_64 kernel-devel-2.6.18-128.1.10.el5.x86_64 kernel-module-xfs-2.6.18-128.1.10.el5-0.4-2.sl5.x86_64

     After the above finished, I double checked the size of
/boot/initrd-2.6.18-128.1.10.el5.img and knew it was too small for things to
have worked, but I rebooted anyways.  It failed to fully boot as it couldn't
mount the XFS file systems.
