No joy in Mudville.

     I started up yumex.  Enabled `sl-testing' and installed the latest yum
update.  After that was finished, I then uninstalled the lastest kernel
update, kernel-2.6.18-128.1.10.el5.x86_64 and the XFS module as well,
kernel-module-xfs-2.6.18-128.1.10.el5-0.4-2.sl5.x86_64.  That finished and I
rebooted the machine into the original kernel,
kernel-2.6.18-128.1.1.el5.x86_64.

     I started up yumex again and installed the lastest kernel and XFS modules
again.  That finished up.  Exited yumex and rebooted.  Same as before, could
not boot up, didn't like the XFS file system.  I had to boot the old kernel
run `mkinitrd' and then I could boot from the new kernel.

     More details.  We have 4 drives, each drive has 4 partitions.  The first
partitions of each drive are mirrored as /boot.  Second partitions are swap.
 3rd partitions are striped as / and the 4th partitions as a data partition.
 All file systems are XFS.

     Am I doing something wrong here?
