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.

With governor performance it switches to 3.5 Ghz and stays
there.

Any Idea how to fix this?

Best regards
