Naah, we wouldn't have broken userspace like that :)

It may be running in *active* mode and you need to put it in *passive* mode.
Try passing following with cmdline:
intel_pstate=passi

Hi!
I test with below two cpu to test:
- Intel(R) Xeon(R) CPU E7-8890 v4 @ 2.20GHz
- Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz
With below action:
make -C cpuidle cpuidle_killer
make -C cpufreq run_tests
And only cpufreq_02 and cpufreq_03 can pass.
