Bug description:
  Today after updating to the linux-image-3.13.0-65-generic 3.13.0-65
  Kernel on Lubuntu 14.04.3 LTS two different programs that rely on
  PySerial quit working. and my ROS (Robot Operating System)
  based Python node quit working.

  When rebooted and selected 3.13.0-63-generic via GRUB everything
  worked again.

  Here are the steps to create the issue with, note that you
  need something connected via a USB to Serial adapter for this to work.
  I am working with a Parallax Activity Board, but an Arduino should
  also exhibit the same behavior.

  sudo apt install linux-image-3.13.0-65-generic
  sudo apt install linux-image-extra-3.13.0-65-generic

   $ /dev/ttyUSB0 115200
  --- Miniterm on /dev/ttyUSB0: 115200,8,N,1 ---
  --- Quit: Ctrl+]  |  Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---

  --- exit ---
  Exception in thread Thread-1:

      raise SerialException('device reports readiness to read but returned no 
data (device disconnected?)')
  SerialException: device reports readiness to read but returned no data 
(device disconnected?)

  Reverting to the 3.13.0-63 kernel allows and other Python
  Serial based programs to work normally.
