Hardy x64 on AMD Turion not CPU scaling properly

[clickwir]

Binary package hint: powernowd

http://ubuntuforums.org/showthread.php?p=4984309#post4984309

I don't know if this is a powernowd problem or a kernel problem. Feel free to change it.

CPU frequency scaling works fine on the same laptop in Win XP and it worked on previous versions of Kubuntu as well.

Crap, sorry. Title should have been 64bit or x64 not, 65.

[janl (janl)]

I was just looking at different things on my media box and noticed that there is no cpufreq at all. My media box runs Gutsy. I know it worked under Feisty.

This is a kernel problem as the modules for cpu scaling does not recognize the cpu.

[clickwir (clickwir)]

Have a link to a bug for that?

Update: Just updated to latest kernel. I know, I saw the change log, there wasn't anything addressing this issue, but I've upgraded anyway.

Similar but not exactly same here, with Core2 CPU T5600/1.83GHz.

No ACPI errors in dmesg

Have you tried upgrading your BIOS?

[clickwir (clickwir)]

The BIOS version available on the mfgr's website is actually older than what mine came with. Well I should say, at least a higher number. I've emailed Acer about this a couple times... they tell me there are no updates to my installed version. It must not be a released version.

Acer Aspire 3004 WLCi

[Arceliar (littlebuzz71)]

Same problem here on a 64bit hardy install with an AMD Sempron processor (family 15).

If nobody has checked yet, I'll probably try doing a 32bit install and see if that kernel's module recognizes the hardware properly (I get the feeling it does, else there'd probably be more bug reports, but that's just a guess).

[thegnark (thegnark)]

Found a post on the forums (http://ubuntuforums.org/showthread.php?t=844754) which seemed to remedy the problem by using kernel 2.6.26.1 and editing /etc/init.d/loadcpufreq or manually loading powernow-k8

[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.

Didn't work for me. Note, I just added a few intrepid repos and then
updated anything just related to 2.6.27 and it's supporting modules.

My Intel wireless Pro/2200BG works fine, automatically picked up and
connected to the network. Seems to be just fine, just no cpu scaling
going on. This is an Acer Aspire 3004 laptop.

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.

[fusion (jlopez2022)]

I have the same problem.
I have an Acer 6530 with AMD turion ultra 7M-80

Whentriying to run ubuntu from live CD, it freezes when loading powernowd service. (I think is a new amd not supported yet)

[David Gaarenstroom (david-gaarenstroom)]

As for the *original* bugreport, this dmesg output:

Jun 26 20:55:57 lappy kernel: [ 494.227246] powernow-k8: BIOS error - no PSB or ACPI _PSS objects

Tells me that your BIOS is broken. This cannot be fixed by the Linux kernel.

Please verify whether there is a more recent BIOS for your system, perhaps your manufacturer has already released a fix. If not, you could request them to do that. Also, perhaps there's a custom ACPI "DSDT" for your system available for Linux that provides a PSB or _PSS table. There are some HOWTO's available that will help you do that.
It could also be that a BIOS option is blocking the PSB or _PSS objects, something in the line of "intelligent power managment" or so. My Asrock motherboard has such an option, I don't remember what it is called.

(I'm not immediately switching the status of this bugreport to "Invalid" as I will wait for your feedback first)

As for all the noise in this bugreport, please fill in your own bug reports...

[David Gaarenstroom (david-gaarenstroom)]

This is definitely not powernowd related

[clickwir (clickwir)]

Yes, a BIOS update was my first thought. Unfortunatly this is an older model and Acer hasn't released an update for years, I doubt they will any time soon.

All I know is that Windows scales fine. I will probably end up getting rid of this laptop instead of trying to get it working, I already have a replacement. Really, the only reason I kept it around was to help provide info for bug reporting. It's taking up space and I could use the money... not that I'd get much.

I can't seem to find what Acer you are using?! My Acer Aspire 5024WLMi should be older, with a Turion ML-34, but its BIOS is fine. Remember that either a PSB or _PSS object is required for Windows 2000 to work!

(Offtopic: I'm actually the writer of the Linux-PHC (Processor Hardware Control) phc-k8 driver and I think I can adapt the phc-k8 driver somewhere in the future to "guess" a powerstate table, without any ACPI usage whatsoever. I may need your help for testing it when it's ready... Maybe (then) I'll even succeed in getting it merged into the vanilla Linux kernel.)

It's an Acer Aspire 3000WLCi.

We have another one in the family that is of the 5000 series and it appears (according to what I can see in the BIOS and on Acer's website) that they use the same BIOS file.

I'm sorry I don't know what PSB or _PSS's are. But what else can I do to help?

I have latest Jaunty on it right now, but the wireless isn't working because it doesn't seem to support WPA2, just WPA.

The Acer Aspire 3000WLCi doesn't seem to come with a Turion ML37, but with a Sempron. Perhaps that's why your BIOS doesn't support it properly? What BIOS version are you using, version "3A32"? Perhaps you can try the "Vista" BIOS as well.

Either PSB or _PSS is required to be present in your BIOS information for Linux frequency scaling to work (if it isn't defined in another way). I just meant that Windows 2000 won't work either if neither are present in your BIOS (ACPI) information.

The Aspire 30xx and Aspire 50xx indeed seem to be alike (and I know for certain 302x and 502x are in fact identical) and there may be a Ferrari notebook that is identical as well, except for its casing. However, I wouldn't know which one is. But the Ferrari's are better and longer supported.

At tuxmobile.org no-one mentions any difficulty with the frequency-scaling of this notebook. Have you tried other Linux distributions/live-CD's? I suspect the Turion is just not supported by the BIOS.

Closing the "linux-meta (Ubuntu)" task as this is already appropriately assigned to the "linux (Ubuntu)" task. Thanks.

Hi clickwir,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . Please then run following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux-image-`uname -r` 231534

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
