** Description changed:

  I'm not entirely sure if this is a thermald issue, but on my laptop
  (Dell XPS 15" 2-in-1) I find that the CPU frequency, under load on AC,
  is often throttled to 2.5GHz rather than the base 3.1GHz or 3.8GHz turbo
  frequency.
  
  Restarting thermald (with `systemctl restart thermald`) will let the
  system scale up to the expected ~3.8GHz boost frequency.
