Thank for your reply. I tried to do what you told me but: sudo modprobe -r speedstep-centrino FATAL: Module speedstep_centrino is in use.
so I tried "sudo modprobe acpi-cpufreq" and: FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.17-10-generic/kernel/arch/i386/kernel/cpu/cpufreq /acpi-cpufreq.ko): Device or resource busy Any clue ? It is very nasty not to have my cpu running at its maximum freq. I also tested the 386 kernel version but it's all the same. -- kernel can't scale cpu frequency https://launchpad.net/bugs/36014 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
