Christopher: I have just commented on this issue a few days ago, how come it doesn't qualify as 'recent activity'?! Yes, this problem is still very much an issue. If you wish, I could also execute the apport command.

[Bug 706089] Re: Frequency scaling doesn't work in current kernels
A.Kromic, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? 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 the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux 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 . Please do not test the kernel in the daily folder, but the one all the way at the bottom. 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. As well, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it. Please let us know your results. Thanks in advance.

[Bug 706089] Re: Frequency scaling doesn't work in current kernels
My problem is described here: http://www.thinkwiki.org/wiki/Problem_with_CPU_frequency_scaling The issue was running with 65W adapter and no battery. However, the laptop happily worked that way at full speed for a long time until the kernel version when that "protection measure" was added, and it worked fine all the time afterwards, first by using the old kernel, and then by using that kernel option. So I guess in this case the kernel protected me from nothing really; I suppose every other R6x/T6x/X6x Thinkpad with that problem can work that way with no ill effects. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/706089 Title: Frequency scaling doesn't work in current kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/706089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Litold: please check your CPU governor - maybe your machine purposely sets the lowest frequency when CPU unloaded... You may also recheck when the CPU is under high load. Another thing I've remembered to mention - it doesn't matter if I boot a 32- or 64-bit system, with both scaling works fine with older kernels up to 2.6.32-24, and doesn't work at all with any newer kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/706089 Title: Frequency scaling doesn't work in current kernels -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
