title: SSH Hangs on "Entering interactive session" stage
body: <p>I built an image with yocto project for Banana Pro board. I am trying to connect port via <code>ssh root@10.1.80.x</code> but I couldn't.</p>
  
  <p>Ssh always hangs on the <code>Entering interactive session</code> stage. When I run <code>ssh -v</code> parameter, I captured below logs :</p>
