Remco, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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-rc4 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 If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER 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. ** Tags added: latest-bios-srosa001.86c needs-upstream-testing regression-potential ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - CPU stalls occur when not using mouse or keyboard + [Clevo M570RU] CPU stalls occur when not using mouse or keyboard -- 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/1044340 Title: [Clevo M570RU] CPU stalls occur when not using mouse or keyboard Status in “linux” package in Ubuntu: Incomplete Bug description: I noticed the problem when playing videos or music. When I don't constantly use the mouse or keyboard (such as continuously tapping on the Up key) the movie stops playing and the music starts repeating the same buffer (the characteristic computer hang sound). When I touch the mouse or keyboard again, the computer continues. In kern.log I found the following line: INFO: rcu_sched detected stalls on CPUs/tasks: { 1} (detected by 0, t=15603 jiffies) So I thought it might have something to do with that.
