Public bug reported: Network interface (NIC) won't respond or work after resuming from suspend to RAM. The device will still appear under commands such as `lshw -c network` or `lspci`, but the network communication will be nonetheless broken.
In my particular case, this happens with a "88E8056 PCI-E Marvell Yukon 2 Gigabit Ethernet Controller". Removing the driver module and adding it back again solves the problem. ``` sudo modprobe -r sky2 && sudo modprobe sky2 ``` Ubuntu 20.04 was also affected by this bug and, from a simple search, this could be a more general regression bug since it affected other drivers in previous releases, e.g. r8169 in Ubuntu MATE 16.04: https://ubuntu-mate.community/t/no-network-via-ethernet-after-resume- from-suspend/7909 ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: linux-modules-extra-5.15.0-46-generic 5.15.0-46.49 ProcVersionSignature: Ubuntu 5.15.0-46.49-generic 5.15.39 Uname: Linux 5.15.0-46-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu82.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: cedricmc 1423 F.... pulseaudio /dev/snd/controlC0: cedricmc 1423 F.... pulseaudio /dev/snd/controlC1: cedricmc 1423 F.... pulseaudio CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Fri Aug 26 15:33:11 2022 InstallationDate: Installed on 2022-08-23 (2 days ago) InstallationMedia: Ubuntu 22.04.1 LTS "Jammy Jellyfish" - Release amd64 (20220809.1) MachineType: Shuttle SX48 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=es_ES.UTF-8 SHELL=/bin/bash ProcFB: 0 VESA VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.15.0-46-generic root=UUID=904aeb07-584e-463f-be63-e883262af847 ro nouveau.blacklist=1 quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-5.15.0-46-generic N/A linux-backports-modules-5.15.0-46-generic N/A linux-firmware 20220329.git681281e4-0ubuntu3.4 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/08/2008 dmi.bios.release: 6.0 dmi.bios.vendor: Phoenix Technologies, LTD dmi.bios.version: 6.00 PG dmi.board.name: FX48 dmi.board.vendor: Shuttle dmi.board.version: V10 dmi.chassis.type: 3 dmi.chassis.vendor: Shuttle Inc dmi.chassis.version: P3 dmi.modalias: dmi:bvnPhoenixTechnologies,LTD:bvr6.00PG:bd10/08/2008:br6.0:svnShuttle:pnSX48:pvrV10:rvnShuttle:rnFX48:rvrV10:cvnShuttleInc:ct3:cvrP3:sku: dmi.product.name: SX48 dmi.product.version: V10 dmi.sys.vendor: Shuttle ** Affects: linux (Ubuntu) Importance: Undecided Status: Confirmed ** Tags: amd64 apport-bug jammy -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1987837 Title: Network (NIC) won't work after suspend Status in linux package in Ubuntu: Confirmed Bug description: Network interface (NIC) won't respond or work after resuming from suspend to RAM.
