Updated the megaraid_sas driver to 5.30 and life is good (thus far).
Thanks for your help.

Both kernels complain about the collision.

But your comment about updating initrd gave me some direction. I copied
the driver from -220 and updated my .57-1 intrd and now I get:

megaraid_sas: disagrees about version of symbol module_layout

So, I download the 5.40 megaraid_sas driver and am attempting to build it:

make -C /lib/modules/2.6.32.57-1.el6xen.x86_64/build M=$PWD modules
make: Entering directory `/usr/src/kernels/2.6.32.57-1.el6xen.x86_64'

I might jump back to 4.33 to see if it will compile without too much
trouble. Thanks for the help.

No change. But I do notice messages booting el6xen that are not present
with the straight up SL6:

pci 0000:02:00.1: BAR 6: address space collision on of device
[0xdc000000-0xdc03ffff]
pci 0000:01:00.1: BAR 6: address space collision on of device

Just having a quick look...

The 2208 is (should?) be supported by the MegaRAID SAS module which is
selected as a module:

config-2.6.32.common:CONFIG_MEGARAID_SAS=m

Maybe you can try rebuilding the initrd with something like:
mkinitrd --preload megaraid_sas <initrd-image> <kernel-version>
