We ran into a problem on our CASes upgrading from 4.1.2.1 to 4.1.3 where the
MPTBase driver would throw a kernel panic on boot up following the upgrade (at
least to the best of what I could figure out that was what it seemed like based
on the error message and timing of the error). Fresh install off the ISO works
fine. Not sure what the difference between the two is, but thought I'd throw it
out there in case somebody else encounters something similar or has a similar
config.

P.S.: The CASes are identical Dell 1850s w/ regular SCSI controllers (no RAID).
The CAM upgrade which have RAID controllers worked without a problem.
