zubu, thank you for reporting this and helping make Ubuntu better. As per http://us.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (2.19). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-2.19 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** 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/1442951 Title: kswapd0 takes 100% of cpu and system is unresponsive Status in linux package in Ubuntu: Incomplete Bug description: it mostly happens, when I open a new tab in Chrome ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: linux-image-3.16.0-34-generic 3.16.0-34.45 ProcVersionSignature: Ubuntu 3.16.0-34.45-generic 3.16.7-ckt8 Uname: Linux 3.16.0-34-generic x86_64 ApportVersion: 2.14.7-0ubuntu8.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: zvi 2645 F.... pulseaudio CurrentDesktop: Unity Date: Sat Apr 11 23:27:30 2015 MachineType: Acer Aspire S7-191 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-34-generic root=UUID=eea9a2dd-b1e4-471d-99a0-54d183006f46 ro quiet elevator=deadline splash vt.handoff=7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Daemon not responding.
