Hi. Please backport upstream commit 8673b83bf2f013379453b4779047bf3c6ae387e4 "acpi-cpufreq: set current frequency based on target P-State" to stable kernels 3.7 and earlier. This patch enables the kernel to control P-states on several platforms. Without this patch, the kernel was unable to control P-states on the same platforms. The upstream patch cleanly applies to 3.7. A backported patch is needed with the removal of SYSTEM_AMD_MSR_CAPABLE for kernels 3.6 and earlier.
