Roman, thank you for testing the latest mainline kernel. Just to clarify:
1) In 13.10, you are noting that when the ondemand governor is used, the frequency of a given CPU doesn't go past 1.8GHz (i.e. Intel Turbo Boost is not taking the frequency past 1.8GHz and up to 3.0GHz)?
2) Did this problem not occur in a release prior to Saucy?

** Changed in: linux (Ubuntu)
       Status: Confirmed => Incomplete
