Description Pepe Perez 2014-03-24 18:46:23 CET
Description of problem:

In Mageia, the driver for Cpupower is acpi-cpufrec for an Intel processor, but for Sandy Bridge, Ivy Bridge and Haswell processors, the driver should be intel_pstate. 

The acpi-cpufrec driver is obsolete, the new driver is intel_pstate.

Version-Release number of selected component (if applicable):

All Kernel-desktop of all versions of mageia (Mageia 3, 4 and Cauldron)

Indeed. I have forgotten to enable it again since I disabled it due to some painful bugs in earlier kernels
Comment 2 Thomas Backlund 2014-04-24 16:06:24 CEST
Fixed in 3.12.18 currently building
Comment 3 Pepe Perez 2014-04-27 10:26:59 CEST
Tested and work fine.
