I guess you mean with the powersave governor.

I would expect schedutil, ondemand and performance to give similar
scores, but for powersave I would expect the score to be lower.

With the same patch applied, can you please switch over to powersave,
reset the stats and then capture the output of

grep -r . /sys/devices/system/cpu/cpufreq/

Also, I'd still like to see the output of

grep . /sys/firmware/acpi/interrupts/sci*
