I have never used this machine with anything less than 15.04, so sorry I
cannot say.

Title:
  Turbo mode on i7 is not enabled upon resume

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Turbo mode is not enabled upon resume from suspend.

  To enable I must issue:

  ``echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo
  echo 1 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo
  echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo``

  I would expect that Turbo was re-enabled by default from resume.

  I created a script in /usr/lib/pm-utils/sleep.d/ to issue the above
  commands, but clearly that mechanism is depreciated.

  I am reporting this bug against systemd as I assume that it is
  managing the running of startup and resume scripts.

  A quick hack solution would be appreciated in the short term.
