title: How to stop 'uninterruptible' process on Linux?
body: <p>I have a VirtualBox process hanging around which I tried to kill (<code>KILL</code>/<code>ABORT</code>) but without success. The parent pid is 1 (init).</p>
  
  <p><code>top</code> shows the process as <code>D</code> which is documented as "uninterruptible sleep".</p>
  
  <p><code>strace</code> shows up nothing.</p>
  
  <p>How can I get rid of this? It prevents me from unloading the VirtualBox kernel driver to load a newer one.</p>
