Viktor Pal, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.
If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-2.65 ** Tags added: latest-bios-2.65 ** Changed in: linux (Ubuntu) Importance: Low => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1506454 Title: kswapd kills the whole OS by eaing up resources Status in linux package in Ubuntu: Incomplete Bug description: I experience that my desktop (Ubuntu 15.04) gets unresponsive maybe once a week. When this happens the whole machine gets unresponsive immediately and only restarting helps. It only turns out from the atop logs what happened after the machine was restarted. Atop is configured to run every 30 secs. It is visible from the atop logs that kswapd0 is eating up all the CPU resources. Strange thing is that this happens despite there is no swap enabled. This happens mostly when Virtualbox is running and only a few amount of memory is available. cat /proc/version_signature Ubuntu 3.19.0-30.34-generic 3.19.8-ckt6 If you need any addition information please let me know.
