https://bugzilla.kernel.org/show_bug.cgi?id=55091 Summary: cpufreq governors woks crazy Product: Power Management Version: 2.5 Kernel Version: 3.9-rc2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: cpufreq AssignedTo: cpufreq@xxxxxxxxxxxxxxx ReportedBy: towo@xxxxxxxxxxxxx Regression: No Since i test kernel 3.9-rc2, cpufreq is crazy with governors ondemand and conservative. Even if the system is idling, cpufreq is on the highest or medium frequency. Only with powersafe i can get the cpu to the lowest frequency. This behavior i cant see in 3.8 or below.
