http://bugzilla.kernel.org/show_bug.cgi?id=15539 Summary: i5 Clarkdale CPUs (e.g., Intel Core i5 6XX) don't respect powersave CPU governor Product: Power Management Version: 2.5 Kernel Version: 2.6.34 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: cpufreq AssignedTo: cpufreq@xxxxxxxxxxxxxxx ReportedBy: t.artem@xxxxxxxxxxxx Regression: No Description of problem: I have enabled the powersave governor on my Intel Core i5 CPU and theoretically the CPU frequency should stay at 1200MHz, however according to i7z utility and temperature sensors, CPU is indeed running at its maximum speed. Version-Release number of selected component (if applicable): all known kernel versions, acpi_cpufreq module How reproducible: always Steps to Reproduce: 1. enable powersave cpu frequency governor 2. run cat < /dev/urandom > /dev/null 3. run i7z utility Actual results: CPU frequency soars to 3200MHz according to i7z *direct* MSR readings, and temperature sensors readings Expected results: CPU speed kept at 1200MHz Additional info: I have Intel Core i5 650 CPU and H55 chipset based motherboard -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
