I sometimes suspend it when moving around the house, but it's often left on all the time. Sometimes when I go to start work in the morning there's some corruption on screen and the laptop won't respond. I can't REISUB or ssh in. This has happened a few times since clean installing 20.04. Previously I was on an upgraded-to-20.04 install and don't recall it happening there. The other obvious difference is I'm now running ZFS which I wasn't before. :S ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-21-generic 5.4.0-21.25 ProcVersionSignature: Ubuntu 5.4.0-21.25-generic 5.4.27 Uname: Linux 5.4.0-21-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu24 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC3: alan 8365 F.... pulseaudio /dev/snd/controlC2: alan 8365 F.... pulseaudio /dev/snd/controlC1: alan 8365 F.... pulseaudio /dev/snd/controlC0: alan 8365 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Wed Apr 8 19:30:46 2020 InstallationDate: Installed on 2020-03-01 (38 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Alpha amd64 (20200301) MachineType: LENOVO 20BV001BUK ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/BOOT/ubuntu_pyyy5h@/vmlinuz-5.4.0-21-generic root=ZFS=rpool/ROOT/ubuntu_pyyy5h ro quiet splash RelatedPackageVersions: linux-restricted-modules-5.4.0-21-generic N/A linux-backports-modules-5.4.0-21-generic N/A linux-firmware 1.187 SourcePackage: linux StagingDrivers: exfat UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 08/14/2019 dmi.bios.vendor: LENOVO dmi.bios.version: JBET73WW (1.37 ) dmi.board.asset.tag: Not Available dmi.board.name: 20BV001BUK dmi.board.vendor: LENOVO dmi.board.version: 0B98417 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrJBET73WW(1.37):bd08/14/2019:svnLENOVO:pn20BV001BUK:pvrThinkPadT450:rvnLENOVO:rn20BV001BUK:rvr0B98417WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad T450 dmi.product.name: 20BV001BUK dmi.product.sku: LENOVO_MT_20BV_BU_Think_FM_ThinkPad T450 dmi.product.version: ThinkPad T450 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1871687/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
