[Bug 97042] Re: Wrong CPU scaling frequencies
I removed the duplicate marking because this is a different bug than #82242. The bug is still alive and kicking in hardy (confirmed with live-cd from 2008-03-14). The problem is that powernowd selects speedstep-centrino driver, which cannot use all available frequencies like the correct acpi-cpufreq driver (see details above in my comment from a year ago). I am not sure if the bug was present in feisty and gutsy, because I fixed it locally by editing /etc/init.d/powernowd to use the correct driver. Anyway, after upgrading to hardy the bug came back. -- Wrong CPU scaling frequencies https://bugs.launchpad.net/bugs/97042 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

*** This bug is a duplicate of bug 82242 *** https://bugs.launchpad.net/bugs/82242 Its not a question of being exactly the same problem, but of having the SAME solution (see last post of bug #82242): The script /usr/share/powernowd/cpufreq-detect.sh would have to be modified to use acpi_cpufreq by default.

[Bug 97042] Re: Wrong CPU scaling frequencies
*** This bug is a duplicate of bug 82242 *** https://bugs.launchpad.net/bugs/82242 Speedstep-centrino (which is now used by default) gives worse frequency scaling choices for me too on Thinkpad X41, compared to acpi-cpufreq. With kernel linux-image-2.6.20-14-generic version 2.6.20-14.22 speedstep-centrino gives: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 798000 1064000 133 1596000 And with acpi-cpufreq: cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 160 150 140 130 120 110 100 90 80 60 So the acpi-cpufreq gives more choices for the frequency and most importantly can go 200mhz lower. This used to work fine a few weeks back, I am not sure when it changed but I think it was kernel version 2.6.20-13.

[Bug 97042] Re: Wrong CPU scaling frequencies
No, it is not your fault. The powernowd script which is launched during the initialisation do, among other things, load the cpufreq driver. This is choosen by calling another script, cpufreq-detect.sh. This script loads, for the intel cpu with the est flag, the speedstep_centrino module. This also means that, unless you change or disable this script, or that you force the unloading/loading of the modules through your own init scripts, that speedstep_centrino will always be loaded. This is obviously wrong in light of this change in the recent kernels, and has to be corrected. -- Wrong CPU scaling frequencies https://launchpad.net/bugs/97042 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for your cooperation Arnold. Please next time it would be better to not tar or compress attachments.

I modprobed -r speedstep_centrino, modprobed acpi-cpufreq, and things seem to be back to normal.

Than it's not powernowd. I think it would be helpful to have a look at your dmesg and syslog. Can you also tell us what modules are loaded (lsmod) as well as give us the output of a cat command of all the files in /sys/devices/system/cpu/cpu0/cpufreq?
