Description Nell Hardcastle 2013-06-28 01:13:06 UTC

Running 3.10-rc7 on an i5-4200U, with either intel_pstate or the older cpufreq drivers the CPU was stuck at 800MHz. I added the model, 0x45, to intel_pstate_cpu_ids and frequency scaling seems to be working as intended now.

Hi Nell,

If this is already solved why not send a patch to dirk and list. And we can get it in quickly. Maybe for 3.11, before Rafael sends a pull request. :)
