I figured out a work around for this bug which i have posted on the ubuntu forums: http://ubuntuforums.org/showthread.php?p=2719839#post2719839
Step 1: Remove Userspace Scaling Software Code: sudo apt-get remove powernowd Step 2: Restart Acpi_cpufreq should no longer be loaded on startup and the processor(s) should be clocked at their full speed but without scaling support. Step 3: Manually load your CPU module I did Code: sudo modprobe acpi-cpufreq Step 4: Load Scaling Modules I was only interested in ondemand, but load the one(s) you need. Code: sudo modprobe cpufreq_ondemand (others) Code: sudo modprobe cpufreq_conservative sudo modprobe cpufreq_powersave sudo modprobe cpufreq_stats sudo modprobe cpufreq_userspace Step 5: Testing/Configuration Show Available Governors Code: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors Select the governor you desire like so Code: sudo -s echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Step 6: Load Modules at Boot Append your selected modules to the end of /etc/modules Code: [Step 3 module] [Modules from Step 4] Mine was Code: acpi-cpufreq cpufreq_ondemand Step 7: Configure Modules at Boot This step needs to be done in order for the modules to retain your settings. Make sure you have sysfsutils installed Code: sudo apt-get install sysfsutils Then add the following lines to /etc/sysfs.conf Code: devices/system/cpu/cpu0/cpufreq/scaling_governor=ondemand devices/system/cpu/cpu1/cpufreq/scaling_governor=ondemand (If you have only one cpu then only the first line would apply) Step 8: Reboot and enjoy Hopefully everything should work now. -- acpi_cpufreq detects intel e6400 with 600 to 800 MHz https://bugs.launchpad.net/bugs/106447 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
