Hello,
My System which runs with older kernels up to 3.13.3
fine on my i3-4330 with 3.5 Ghz and governor powersave.
and pstate driver.
With kernel 3.14-rc3 and Governor powersave it runs
only at 770Mhz and never switches to higher Freq. on load.
Even compiling a kernel with make -j4 does not change freq.
commit fcb6a15c2e7e76d493e6f91ea889ab40e1c643a4 seems to be the culprit
With governor performance it switches to 3.5 Ghz and stays
there.
Any Idea how to fix this?
Greg KH is seeing the same thing on his Haswell system. I am trying
to figure what went south.

Can you send me the .config for the broken kernel also the output of
gcc -v
Best regards
Hello
I reverted the mentioned commit.
it now seams to work. But total idle power comsumption is aprox. 5 Watts
higher as
running kernel 3.13.3. Measured with a true rms powermeter on primery side.
This is the bug the commit was trying to fix :-) It works well on the test
systems I have, I am building up a Haswell test system to add to my stable.
Could you send me your whole .config file?
