dev.cpu.0.freq_levels

Wed Nov 15 10:24:21 UTC 2017

Hello, I'am Piotr.

Please help me someone, if there is any possibility to fix problem on my notebook.
I cannot force my Pentium M 770 to work at desired factory frequency of 2,13 GHz.
It runs only at 1862 MHz!
I think it is acpi problem.
To help I am adding some system messages.
