** 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. --- 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.
