title: nvidia-smi process hangs and can't be killed with SIGKILL either
body: <p>I'm on Ubuntu 14.04, CUDA toolkit 8, <strong>driver version 367.48</strong>.</p>
  
  <p>When I give <code>nvidia-smi</code> command, it just hangs indefinitely.
  When I login again and try to kill that <code>nvidia-smi</code> process, with <code>kill -9 &lt;PID&gt;</code> for example, it just isn't killed.
  If I give another <code>nvidia-smi</code> command, I find both the processes running - of course when logging from another shell, because that gets stuck as before.</p>
  
  <p>Can it be an issue related to the driver?
  It's not the latest, but still quite new..</p>
