I rebooted and dmesg, in fact, starts with this line, and it repeats
300 times. The next line after that is the version of the MPT driver,
3.01.16.

Are you saying that MPT driver is seeing some garbage data where
there should be valid data structures and that garbage data is being
generated by the external hardware RAID attached to the card (the
only thing attached to it).
