    I can't address the cause of the problem; but I have had good luck using

       camcontrol reset <all | bus[:target:lun]>

    when my tape device wedges. This is less disruptive than a reboot. Use:

       camcontrol devlist -v

    To get a list of your busses and such if you can't remember the ID of
    the drive in question (I'm too lazy to walk over to the rack...).
