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
Cool, after use this kernel_cmdline, 4\5\6\8 can pass now, but 1\7\9 still can not: cpufreq_01.0/cpu0: checking 'scaling_available_frequencies' exists in '/sys/devices/system/cpu/cpu0/cpufreq'...
