Title:
  CPUs get stuck in Turbo mode after a suspend/resume cycle on a
  ThinkPad X220

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Often, but not always, after I suspend and resume my ThinkPad X220, I
  notice that the laptop becomes hot, the fan is constantly spinning,
  and powertop shows all four CPUs stuck at 2.5 GHz.

  Suspending and resuming again fixes the issue.
