I believe the bisect is done: Building this commit causes the ethernet to work after reboots. (a PHY problem seems to make sense as there's no link lights).

I am able to cold boot it with the network cable unplugged and then the ethernet works as expected after re-plugging the ethernet. Workaround: I have installed the latest mainline kernel from https://github.com/pimlie/ubuntu-mainline-kernel.sh which appears to solve the issue. (vmlinuz-5.9.3-050903-generic) This issue looks similar although I wasn't able to find the firmware for my motherboard so I didn't try the solution: https://askubuntu.com/questions/1244745/ubuntu-20-04-intel-network-connectivity-issue-bug-in-igc I found here that I could cold boot and it would work: https://ubuntuforums.org/showthread.php?t=2444239 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-52-generic 5.4.0-52.57 ProcVersionSignature: Ubuntu 5.4.0-52.57-generic 5.4.65 Uname: Linux 5.4.0-52-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.10 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: apatterson 3328 F.... pulseaudio /dev/snd/controlC1: apatterson 3328 F.... pulseaudio /dev/snd/controlC2: apatterson 3328 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Nov 2 14:10:10 2020 InstallationDate: Installed on 2020-10-23 (9 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) MachineType: ASUS System Product Name ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.4.0-52-generic root=UUID=5254abc1-6ff1-4753-96c8-97b84156de0b ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.4.0-52-generic N/A linux-backports-modules-5.4.0-52-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: American Megatrends Inc. dmi.bios.version: 1004 dmi.board.asset.tag: Default string dmi.board.name: ROG STRIX B550-F GAMING (WI-FI) dmi.board.vendor: ASUSTeK COMPUTER INC. dmi.board.version: Rev X.0x dmi.chassis.asset.tag: Default string dmi.chassis.type: 3 dmi.chassis.vendor: Default string dmi.chassis.version: Default string dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1004:bd08/13/2020:svnASUS:pnSystemProductName:pvrSystemVersion:rvnASUSTeKCOMPUTERINC.:rnROGSTRIXB550-FGAMING(WI-FI):rvrRevX.0x:cvnDefaultstring:ct3:cvrDefaultstring: dmi.product.family: To be filled by O.E.M. dmi.product.name: System Product Name dmi.product.sku: SKU dmi.product.version: System Version dmi.sys.vendor: ASUS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1902578/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
