Kamin Punpipat, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-14-3421/drivers an update to your BIOS is available (A12). 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
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. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Once the BIOS is updated, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-a12 ** Changed in: linux (Ubuntu) Importance: Undecided =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/1379764 Title: System Hanged and Freeze Status in “linux” package in Ubuntu: Incomplete Bug description: Normally I was experienced system hanged (sometime is freeze) more than 10 times because I opened up to 10 tabs in google-chrome. But now I think this problem came from kernel because I was reduced my applications usage but sometime is still hang or freeze. Ubuntu booted more than approx 30 second. And logged in approx 30 second. But not mean my system is slow, I install 4 GB ram and system see 3.8 GB (normal) and Quad-CPU 1.8 GHz from Intel. And I did not used SSD. I Tweak my system by enable swap zram Now my system was hang and freeze again. No things happen when press (Alt+Fn+PrntScr (Which is SysRQ button) + F). I was press this to made system restart (Alt+Fn+PrntScr+R, E, I, S, U, B) and system was restarted. I was config this to make system not be freeze but cannot. /etc/sysctl.conf : vm.swappiness=10 vm.oom_kill_allocating_task=0 vm.overcommit_memory=0 vm.overcommit_ratio=99 vm.laptop_mode=5 Which about VM of Kernel Config. Before system freeze I found that my free ram space very low (Free Mem approx 180MB, Free Buffer/Cache approx 650MB) ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-37-generic 3.13.0-37.64 ProcVersionSignature: Ubuntu 3.13.0-37.64-generic 3.13.11.7 Uname: Linux 3.13.0-37-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/controlC0', '/dev/snd/hwC0D0', '/dev/snd/hwC0D3', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/pcmC0D3p', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: XTERM Date: Fri Oct 10 17:19:39 2014 HibernationDevice: RESUME=UUID=71ac432f-0009-48e0-85c1-272ee61c1ed6 InstallationDate: Installed on 2014-01-08 (274 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: Dell Inc.
