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The acpi-cpufrec driver is obsolete, the new driver is intel_pstate.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)
Steps to Reproduce:
Indeed. I have forgotten to enable it again since I disabled it due to some painful bugs in earlier kernels
Fixed in 3.12.18 currently building
Tested and work fine.
