thomerz, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** This bug is no longer a duplicate of bug 206864 Unable to set max_cstate without rebooting (since hardy) ** Tags added: needs-kernel-logs needs-upstream-testing -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/93067 Title: High pitch noise from CPU when on battery Status in “linux” package in Ubuntu: Incomplete Status in “linux-source-2.6.20” package in Ubuntu: Won't Fix Bug description: Binary package hint: linux-source-2.6.20 Hi, I have a very annoying nigh pitch noise on all of my newer laptops (hp nx8220, nw-series, thinkpad x60 and x60s) when on battery, cpu is idling on lowest step and no usb device is plugged in, as descripted here: http://www.thinkwiki.org/wiki/Problem_with_high_pitch_noises #Solutions_for_CPU-triggered_noise # echo 2 > /sys/module/processor/parameters/max_cstate solves the problem for me, although it was not necessary to do anything in edgy (all 2.6.17* kernels there). I don't know if you need any further information here, because it seems this problem exists with nearly every new laptop and kernel or distribution, except the one used in edgy.
