[Bug 365798] Re: cpu frequency scaling not supported after upgrading to 9.04
Mike Rose, thank you for reporting this and helping make Ubuntu better. Jaunty reached EOL on October 23, 2010. Please see this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We were wondering if this is still an issue on a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command in a supported release from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux replace-with-bug-number 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. ** Tags added: jaunty needs-upstream-testing regression-release ** Attachment removed: cpufreq.txt https://bugs.launchpad.net/ubuntu/+source/linux/+bug/365798/+attachment/571456/+files/cpufreq.txt ** Attachment removed: cats.txt https://bugs.launchpad.net/ubuntu/+source/linux/+bug/365798/+attachment/571472/+files/cats.txt ** Attachment removed: lsmod.txt https://bugs.launchpad.net/ubuntu/+source/linux/+bug/365798/+attachment/571943/+files/lsmod.txt ** Attachment removed: cpufreq_issues.tar.gz https://bugs.launchpad.net/ubuntu/+source/linux/+bug/365798/+attachment/594683/+files/cpufreq_issues.tar.gz ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/365798 Title: cpu frequency scaling not supported after upgrading to 9.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/365798/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 365798] Re: cpu frequency scaling not supported after upgrading to 9.04
During my work with linux-phc I noticed that some combinations of Intel Pentium M (centrino based) CPUs and BIOSes fail to work using acpi- cpufreq but working with speedstep-centrino. The problem is somewhere within the ACPI subsystem that decides that the system lacks some needed functionality (- SYSTEM_IO_CAPABLE instead of SYSTEM_MSR_CAPABLE). Until 8.10 the speedstep-centrino did the work. Not that the Ubuntu devs decided to compile-in processor drivers speedstep-centrino can not work (because acpi-cpufreq blocks the device since it took over the functions). The only way to those certain users will be to compile their own kernel and set acpi-cpufreq as module again (or completely remove it) to be able to use speedstep-centrino again. -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 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

[Bug 365798] Re: cpu frequency scaling not supported after upgrading to 9.04
Mats, the bug you describe is a different one. This one is about frequency scaling being not supported, while your output states 5 supported frequency steps. I've solved the problem on my Asus P5B-E motherboard but upgrading to the latest BIOS. It still persists with the Quadcore and Atom machines that I've tested. Since quite a few people seem to be able to solve this via BIOS up- or downgrades, it seems Linux / Ubuntu is not the one to blame. -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 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

The bug still exists for me on my Dell Vostro 1700, and my computer only runs at 800MHz which makes it slow and unsuitable for watching HDTV movies. I installed the cpufrequtils and ran cpufreq-info, se output below. The most interesting line is probably: current policy: frequency should be within 800 MHz and 800 MHz.

[Bug 365798] Re: cpu frequency scaling not supported after upgrading to 9.04
It looks like powernowd package is not installed by default on upgrade to 9.04. At least this turned out to be my case: after installing the missing package manually, I've got freq-scaling back working (though somewhat less comfortable than in 8.10). -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 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

It should be pretty much useless at this point because the kernel can do this stuff itself, so the fact that you need it installed is a bug.

I rebooted, and was right back where I started from (i.e. scaling not working, cpu freq set at 2.19). I did the modprobe again, and added the acpi-cpufreq, rebooted, and everything works correctly... I attached the files you requested, let me know if you need anything else. Thanks, but if it is working for you then those files aren't that much use. As I said, if you are running the Jaunty kernel then it shouldn't even be possible to load that module, so something is odd. Please provide the output of modinfo acpi-cpufreq Thanks, James -- cpu frequency scaling not supported after upgrading to 9.04 https://bugs.launchpad.net/bugs/365798 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
