I had a similar problem on my Asus U43JC which runs on an Intel i5-450m (using Ubuntu 10.10). The BIOS would limit my frequence at 1.2GHz, no matter what cpufreq governor I was using, no matter if on the power cord or on the battery. To fix this, I added "processor.ignore_ppc=1" to the kernel boot parameters.
To see if you have the same problem, do a: $ cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit In my case, anything less than 2400000 means the workaround is necessary. To implement it, just add "processor.ignore_ppc=1" to the GRUB_CMDLINE_LINUX_DEFAULT paramenter in /etc/default/grub, and then run: $ sudo update-grub Reboot. -- [maverick] CPU frequency does not scale up unless all cores are in use https://bugs.launchpad.net/bugs/637845 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
