Title:
  Dell M4600 very slow after resume

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Dell M4600 (BIOS A10) with Ubuntu 12.04 64-bit. If I suspend the
  device while un-docked and then resume, my laptop is very slow and
  turbostat shows that I am stuck at about 600MHz for all cores, even
  when there is significant load:
