In fact, i has used intel_pstate driver: $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver intel_pstate
It may be running in *active* mode and you need to put it in *passive* mode.
Try passing following with cmdline:
intel_pstate=passive
I don't know the passive / active mode but the path changed.
/sys/devices/system/cpu/cpufreq/policy[0-9]/scaling_driver
So there is probably something to do in PM-QA.
