Public bug reported: Running LTS 14.04 on my X220 in a docking station. Frequently the laptop freezes up for extended periods. Sometimes I get a couple of keypresses in but often it's frozen for nearly a minute before I can do anything.
Typically afterwards I can look in dmesg and see the cpu overheating (I've previously had the fan replaced, and very recently had the laptop apart to clean dust out). The syslog is also being spammed with:- [169246.385121] powercap intel-rapl:0: package locked by BIOS, monitoring only http://paste.ubuntu.com/15568114/ is my dmesg ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-4.2.0-34-generic 4.2.0-34.39~14.04.1 ProcVersionSignature: Ubuntu 4.2.0-34.39~14.04.1-generic 4.2.8-ckt4 Uname: Linux 4.2.0-34-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 CurrentDesktop: Unity Date: Thu Mar 31 15:30:21 2016 InstallationDate: Installed on 2015-12-23 (98 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) SourcePackage: linux-lts-wily UpgradeStatus: Upgraded to trusty on 2016-01-28 (62 days ago) ** Affects: linux-lts-wily (Ubuntu) Importance: High Assignee: Colin Ian King (colin-king) Status: In Progress ** Tags: amd64 apport-bug third-party-packages trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1564443 Title: System freezes, dmesg spammed, overheating laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-wily/+bug/1564443/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
