Title:
  Kernel upgrade to linux-image-3.16.0-28-generic breaks my external
  keyboard

Status in linux package in Ubuntu:
  Expired

Bug description:
  With linux-image-3.16.0-25-generic, everything works fine. With linux-
  image-3.16.0-28-generic, if I boot with an external keyboard attached,
  the keyboard generates keypress events only until I close my laptop
  lid. After closing the lid, presses on the USB keyboard generate no
  events. This state of affairs persists even after opening the laptop
  lid again.

  Booting with the previous kernel using the GRUB menu option restores
  correct behavior. Switching to a non-X VT and using evtest indicates
  that no events are being delivered to userland. dmesg doesn't report
  any unusual messages across lid close and reopen.

  Repro:

  1) Boot with laptop lid open and external USB keyboard attached
  2) Log into X
  3) Type using external keyboard: note that keypresses are received
  4) Close laptop lid (using external monitor)
  5) Type on external keyboard: does nothing
  6) Open laptop lid
  7) Type on external keyboard: does nothing
