Title:
  HP Chromebook Touchpad broken in 3.11.0-14 kernel

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On upgrading from linux-image-3.11.0-13-generic to linux-
  image-3.11.0-14-generic, the touchpad on the new HP Chromebook 14
  doesn't respond at all. Opening up the system settings for mouse and
  touchpad shows only settings for the mouse. Booting with 3.11.0-13
  kernel restores touchpad and shows settings in the control panel.
