Could you run "powertop --html" before and after resume and attach the
results.

OK, attached. Another strange thing. I think I have never noticed before,
because I have this laptop since a couple of days. After I have booted cpufreq
showed 2.80ghz at all cores without any last. THen I have executed
max_perf_pct showed 100
and min_perf_pct showed 21
I has never gone below 2.80Ghz
After I have executed
echo 21 > /sys/devices/system/cpu/intel_pstate/max_perf_pct
it went down to 800Mhz as expected in cpupower tool view
genlap ~ # cpupower -c 0-4 frequency-info | grep current
current policy: frequency should be within 800 MHz and 3.80 GHz.
current CPU frequency is 800 MHz (asserted by call to hardware).
current policy: frequency should be within 800 MHz and 3.80 GHz.
current CPU frequency is 800 MHz (asserted by call to hardware).

current CPU frequency is 800 MHz (asserted by call to hardware).
current CPU frequency is 800 MHz (asserted by call to hardware).
When I put the value 100 in the max_perf_pct it goes now between 2.80 and
somewhere 3.30Ghz and changes all the time as I execute cpupower.
But, before I have touched this max_perf_pct after the boot it was constantly
on 2.80.
With regards,
Lado
