At first I had smartd running as well which was scheduled much later in 
the morning away from the 3dmd verify.  I experimented by not running 
smartd but the crashes still occurred.

The port0 error was after every crash.

I would not feel right trying to report this to RH bugzilla.  Is that 
something that has been done in the past?  I am just really surprised 
that RH has not found this problem on their own.  3ware controllers are 
used by a lot of users I would think.  To have a problem like this is a 
pretty big deal I would think.
