Title:
  System hang with Virtualbox & kernel 4.13.0-32-generic

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Some (maybe all) kernels in the 4.13.0 series are hanging with
  Virtualbox on my Ubuntu 16.04 laptop. When I try to launch a
  Virtualbox VM, the VM's window appears, clears to black, and then the
  mouse freezes. I do NOT see any BIOS/EFI information or boot loader in
  the VM; the hang occurs before those messages appear. (I've tried this
  with the VM set for both BIOS and EFI booting with no difference.) The
  host computer also stops responding to pings or anything else; the
  only solution seems to be to do a cold reset. I've tested this on a
  different computer running the same kernel and the latest Ubuntu 18.04
  alpha and had no problems there. Here's some data from the affected
  computer:

  $ lsb_release -rd
  Description:  Ubuntu 16.04.3 LTS
  Release:      16.04

  $ cat /proc/version_signature 
  Ubuntu 4.13.0-32.35~16.04.1-generic 4.13.13

  $ dpkg -s virtualbox | grep Version
  Version: 5.0.40-dfsg-0ubuntu1.16.04.2

  This problem does NOT occur with earlier kernels, such as those in the 4.4.0 
series.
