Bug description:
  After updating the kernel inside the virtual machine to the version 4.4.0-67-generic, at the next boot the vm will stuck in a black screen at every try. An hard reset is required.
  The only workaround is to set the default in grub to the previous version.
  The virtual machine hardware is a Gen2.
  We are experiencing this issue on all our vps with the same kernel (around 300-400 vms).
