Public bug reported: Frequently, returning from suspend, the lock screen 'crashes'. I typically enter my password, it freezes (sometimes shows me my desktop) and then I get the lock screen again, presumably it's respawned. My syslog shows a kernel stack trace and "drm/i915: Resetting chip after gpu hang"
Just before reporting this it happened twice before I got past the lockscreen to my desktop ---- ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-24-generic 4.4.0-24.43 ProcVersionSignature: Ubuntu 4.4.0-24.43-generic 4.4.10 Uname: Linux 4.4.0-24-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: james 1988 F.... pulseaudio CurrentDesktop: Unity Date: Sun Jun 12 20:58:31 2016 EcryptfsInUse: Yes InstallationDate: Installed on 2016-05-21 (22 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: LENOVO 2325KZ5 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-24-generic root=UUID=72122534-7dd5-411b-9c56-c4844502e0ad ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-4.4.0-24-generic N/A linux-backports-modules-4.4.0-24-generic N/A linux-firmware 1.157 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/05/2013 dmi.bios.vendor: LENOVO dmi.bios.version: G2ETA0WW (2.60 ) dmi.board.asset.tag: Not Available dmi.board.name: 2325KZ5 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: 518896 dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrG2ETA0WW(2.60):bd03/05/2013:svnLENOVO:pn2325KZ5:pvrThinkPadX230:rvnLENOVO:rn2325KZ5:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2325KZ5 dmi.product.version: ThinkPad X230 dmi.sys.vendor: LENOVO ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1591790 Title: Resume from suspend, lock screen causes gpu hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1591790/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
