Title:
  [REGRESSION] Kernel update renders Intel NUC (i5-3427) unbootable with
  USB devices plugged in

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The latest kernel update in Ubuntu 14.04 LTS (3.13.0-32.57) renders
  our Intel NUCs unbootable, when we cold boot and have USB devices
  (keyboard, mouse, USB/Ethernet adapter) connected.

  The 3.13.0-24.47 kernel does not exhibit this behavior.

  Our particular NUCs have the i5-3427U processor, which is the
  D53427RKE board (DC53427HYE kit).
