apport information ** Tags added: apport-collected hirsute
** Description changed: I recently got a Thinkpad T14 Gen2 with a I219-V network adapter (8086:15fc). I get very slow connection speeds and even total loss of connectivity without seeing much in the logs (like dmesg etc.). ethtool reports CRC errors and paket loss. Besides Ubuntu 21.04/kernel 5.11 I tried to install Ubuntu 20.04 (kernel seems to old) and i tried the e1000e driver directly from upstream (3.8.7) with no success. A strange behaviour I observed: if connectivity is lost (notebook is not reachable via ping from another host), if I do something like "ping 8.8.8.8" on the notebook itself, it becomes reachable from the other host again. Downloads in general are very slow if they work at all. - WLAN (AX210) seems to work fine, wired network using a USB-network - adapter works fine, too. + WLAN (AX210) seems to work fine, wired network using a USB-network adapter works fine, too. + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu65 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: ros 3285 F.... pulseaudio + CasperMD5CheckResult: pass + DistroRelease: Ubuntu 21.04 + HibernationDevice: RESUME=none + InstallationDate: Installed on 2021-05-07 (2 days ago) + InstallationMedia: Ubuntu 21.04 "Hirsute Hippo" - Release amd64 (20210420) + MachineType: LENOVO 20W0004MGE + NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair + Package: linux (not installed) + ProcFB: 0 i915drmfb + ProcKernelCmdLine: BOOT_IMAGE=/BOOT/ubuntu_n51dtp@/vmlinuz-5.11.0-16-generic root=ZFS=rpool/ROOT/ubuntu_n51dtp ro quiet splash vt.handoff=1 + ProcVersionSignature: Ubuntu 5.11.0-16.17-generic 5.11.12 + PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon. + RelatedPackageVersions: + linux-restricted-modules-5.11.0-16-generic N/A + linux-backports-modules-5.11.0-16-generic N/A + linux-firmware 1.197 + Tags: hirsute + Uname: Linux 5.11.0-16-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: N/A + _MarkForUpload: True + dmi.bios.date: 03/10/2021 + dmi.bios.release: 1.10 + dmi.bios.vendor: LENOVO + dmi.bios.version: N34ET21W (1.10 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 20W0004MGE + 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: 1.8 + dmi.modalias: dmi:bvnLENOVO:bvrN34ET21W(1.10):bd03/10/2021:br1.10:efr1.8:svnLENOVO:pn20W0004MGE:pvrThinkPadT14Gen2i:rvnLENOVO:rn20W0004MGE:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: + dmi.product.family: ThinkPad T14 Gen 2i + dmi.product.name: 20W0004MGE + dmi.product.sku: LENOVO_MT_20W0_BU_Think_FM_ThinkPad T14 Gen 2i + dmi.product.version: ThinkPad T14 Gen 2i + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1927925/+attachment/5496124/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927925 Title: Massive network problems with I219-V on Thinkpad T14 Gen2 (e1000e) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927925/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
