Title:
  Virtualbox host broken on Broadwell CPUs

Status in Virtualbox:
  Unknown
Status in virtualbox package in Ubuntu:
  Fix Released
Status in virtualbox source package in Trusty:

Bug description:
  Due to VirtualBox #13820 [1], Linux hosts running on Broadwell CPUs
  are unable to start VirtualBox VMs.

  Launching a VM hangs at 0%, and logs dmesg output like this:

  [ 6204.331045] BUG: unable to handle kernel paging request at
  00007f6f95a043e0

  This issue was reportedly fixed in version 4.3.22.

  Given that this bug makes VirtualBox entirely unusable on affected
  machines, this seems like a plausible candidate for an SRU release.
