With CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y (linux-pm.git#linux-next) I get...

$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_driver
acpi-cpufreq
acpi-cpufreq
acpi-cpufreq
acpi-cpufreq

$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
ondemand
ondemand
ondemand
ondemand

...is there a difference when using intel_pstate as scaling_driver?
Are the scripts of Ubuntu working properly with acpi-cpufreq (only)?
