CAM status: CCB request completed with an error

Wed Apr 2 10:48:29 UTC 2014

What the bleep is a "CCB request", and why would it fail, over and over and over
again, ad infinitum?

Obviously, this has something to do with the second drive in my system, but I
mean seriously (?) Come on!  Did somebody fail to implement some logic that
would recognize when there have been several thousand such errors already
logged and then, you know, avoid filling up /var/log/messages with even more
of these utterly incomprehensible (and thus utterly useless) error messages?
