I've tried the kernel listed in the certification above, 5.4.0-33-generic, the installed kernel, 5.4.0-42-genric, the updated kernel, 5.4.0-47-generic, all without success. I've tried disabling various features (disable_11ac=Y disable_11ax=Y disable_11n=1), also without success. (Ignore the mt76x0u device in logs, it was a wireless USB dongle I added in order to file the bug report) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-modules-extra-5.4.0-47-generic 5.4.0-47.51 ProcVersionSignature: Ubuntu 5.4.0-47.51-generic 5.4.55 Uname: Linux 5.4.0-47-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: twalker 2104 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Fri Sep 18 20:19:56 2020 InstallationDate: Installed on 2020-09-18 (0 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) MachineType: LENOVO 20UAS01W00 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.4.0-47-generic root=UUID=47f8ab08-579c-40bb-9181-57e14d2853dd ro quiet splash RelatedPackageVersions: linux-restricted-modules-5.4.0-47-generic N/A linux-backports-modules-5.4.0-47-generic N/A linux-firmware 1.187.3 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 08/13/2020 dmi.bios.vendor: LENOVO dmi.bios.version: N2WET21W (1.11 ) dmi.board.asset.tag: Not Available dmi.board.name: 20UAS01W00 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.modalias: dmi:bvnLENOVO:bvrN2WET21W(1.11):bd08/13/2020:svnLENOVO:pn20UAS01W00:pvrThinkPadX1CarbonGen8:rvnLENOVO:rn20UAS01W00:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad X1 Carbon Gen 8 dmi.product.name: 20UAS01W00 dmi.product.sku: LENOVO_MT_20UA_BU_Think_FM_ThinkPad X1 Carbon Gen 8 dmi.product.version: ThinkPad X1 Carbon Gen 8 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896303/+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
