https://bugzilla.kernel.org/show_bug.cgi?id=58801 --- Comment #3 from Christoph Loehr <c.h.l@xxxxxx> 2013-05-25 14:57:21 --- In the meantime I have made a git bisect between kernel 3.9.2 and 3.9.3 with the following result: 5aacc8bcf0b23e20cbb205ac6fdc3ce797e1cae2 is the first bad commit commit 5aacc8bcf0b23e20cbb205ac6fdc3ce797e1cae2 Author: Dirk Brandewie <dirk.j.brandewie@xxxxxxxxx> Date: Tue May 7 08:20:25 2013 -0700 cpufreq / intel_pstate: remove idle time and duration from sample and calculations commit 1abc4b20b85b42e8573957e54b193385cf48b0d6 upstream. In order to confirm this is the relevant commit I have compiled a 3.9.3 kernel where I had reverted the changes provided by this commit. With this kernel booted the frequency switching works again. I hope that helps.
