Without a stack trace, it's going to be extremely difficult to say what caused the panic, and without some cause, we can't come up with a solution. So, without some more information, there's very little we can do to help with the panic. As for the two errors above, I'm CCing this to Matthew Jacob <mjacob@feral.com> who is the current maintainer of the CAM tape driver. He may be interested in them.
