>Description:
      I have a nikon coolpix 2200 digital camera.  The camera has internal memory and a memory card in.  When the memory card is in it works fine.  I can plug the camera into the usb and type:
      #mount -t msdosfs /dev/da0s1 /cam
get what I need off the camera and then type
      #umount /cam
However, when there is no memory card in the camera the system cannot umount it.  Shortly after, the system freezes.
>How-To-Repeat:
      plug in the camera.  As root type
       #mount -t msdosfs /dev/da0s1 /cam
       #umount /cam
