apport information

** Tags added: apport-collected

** Description changed:

  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
