Screen is frozen, mouse cursor frozen and the only chance to recover is to switch off. Since it is hard to tell which part is broken I appended the kernel logs of the last boot. I found two "------------[ cut here ]------------" in the logs which seems to be a bad sign. I tried different kernels 5.8.0-36, 5.8.0-38, 5.8.0-40 and a 5.10.8 from the kernel team. All freeze. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu50.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: haug 2161 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.10 InstallationDate: Installed on 2019-09-26 (483 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) MachineType: LENOVO 20LS001AGE Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.8.0-40-generic root=UUID=39812da1-4b85-4eac-bf54-de26c89ea52f ro rootflags=subvol=@ psmouse.elantech_smbus=0 quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.8.0-40.45-generic 5.8.18 RelatedPackageVersions: linux-restricted-modules-5.8.0-40-generic N/A linux-backports-modules-5.8.0-40-generic N/A linux-firmware 1.190.3 Tags: groovy wayland-session Uname: Linux 5.8.0-40-generic x86_64 UpgradeStatus: Upgraded to groovy on 2021-01-09 (12 days ago) UserGroups: sudo WifiSyslog: _MarkForUpload: True dmi.bios.date: 08/05/2020 dmi.bios.release: 1.40 dmi.bios.vendor: LENOVO dmi.bios.version: R0QET63W (1.40 ) dmi.board.asset.tag: Not Available dmi.board.name: 20LS001AGE dmi.board.vendor: LENOVO dmi.board.version: SDK0J40697 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.ec.firmware.release: 1.40 dmi.modalias: dmi:bvnLENOVO:bvrR0QET63W(1.40):bd08/05/2020:br1.40:efr1.40:svnLENOVO:pn20LS001AGE:pvrThinkPadL480:rvnLENOVO:rn20LS001AGE:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad L480 dmi.product.name: 20LS001AGE dmi.product.sku: LENOVO_MT_20LS_BU_Think_FM_ThinkPad L480 dmi.product.version: ThinkPad L480 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912646/+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
