No cool n' quiet for amd phenom processors

[gwydion.dot]

I've installed Ubuntu hardy (last version). When I log in into gnome, I get the message my CPU can't use the cool n' quiet mode.
I think there is something missing in the kernel, on my gentoo installation it will work very well.

Hi gwydion.dot,

Care to take screenshot of the message you see and attach it to this bug report. Also care to attach your full dmesg output? Thanks.

Any news on this? I'm running a Phenom 9500 and would really like to be able to use this. I'm running Hardy Alpha 6.

[Robert Rettig (info-robert-rettig)]

Any news?

[Robert Rettig (info-robert-rettig)]

i solved that problem by installing packages
cpufreqd
cpufrequtils

and inserting the module
powernow-k8
in /etc/modules

patching the module powernow-k8 for resolving the new cpu phenom automatically would be the best

[Adam Petaccia (mighmos)]

I can confirm zf5WY05x3fmAYrtD's work-around.

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Leann:
The problem is not with that kernel, the problem is with powernowd not loading powernow-k8 because its script at /usr/share/powernowd/cpu-detect.sh is setup only for k8 processors with family 15. I've filed a separate bug report with included patch to enable Phenom and newer mobile Turion chips to function. The 2.6.27 kernel that's been released for Intrepid so far works with that patch and allows these processors to function properly.

Bug is located here: https://bugs.launchpad.net/ubuntu/+source/powernowd/+bug/261608

For my mobile Turion (family 17) the patch enables the powernow module without the need to install additional packages.
For Hardy, the script should work for Phenom, but the kernel module will not support these Turion chips according to my tests. If you have such a module, that patch will make powernowd load the module for your chip and fail, causing Ubuntu to hang at boot.

Summary: Hardy's kernel works with Phenom but needs a minor patch in powernowd's script to load the module. Intrepid supports Phenom and the new Turion chips, but needs a similar patch. In both cases no additional packages need to be installed.

[Leann Ogasawara (leannogasawara)]

Thanks for the update. Reassigning this to powernowd and will mark as a dup of 261608. Thanks.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
