Latest kernel where network card works: linux-image-4.15.0-20-generic 4.15.0-20.21~16.04.1 amd64 Signed kernel image generic Tested kernels where network card breaks: 4.15.0-22 4.15.0-33 4.15.0-36 # lspci -nn -d ::0200 00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:15bb] (rev 10) BIOS Information Vendor: Dell Inc. Version: 1.2.14 Release Date: 09/06/2018 To reproduce the issue: 1. Install any kernel starting on 4.15.0-22 or above 2. Boot the machine with the new kernel 3. ping the gateway (pings are in the sub 1ms range) 4. Attempt to do things that use the network, i.e. apt update or scp, etc. It may take a minute or so before things get hung, i.e. you will see apt update progress stop and the transfer rate drop down to just a few kb/s or simply say stalled. 4. Now ping the gateway again and you will see 1-5s pings, dropped packets 5. At this point network is no longer usable ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-generic-hwe-16.04 (not installed) ProcVersionSignature: Ubuntu 4.15.0-20.21~16.04.1-generic 4.15.17 Uname: Linux 4.15.0-20-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.18 Architecture: amd64 CurrentDesktop: Unity Date: Fri Oct 19 10:35:08 2018 InstallationDate: Installed on 2016-08-25 (784 days ago) InstallationMedia: It ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: linux-meta-hwe UpgradeStatus: No upgrade log present (probably fresh install) --- ApportVersion: 2.20.1-0ubuntu2.18 Architecture: amd64 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/hwC0D2', '/dev/snd/hwC0D0', '/dev/snd/pcmC0D10p', '/dev/snd/pcmC0D9p', '/dev/snd/pcmC0D8p', '/dev/snd/pcmC0D7p', '/dev/snd/pcmC0D3p', '/dev/snd/pcmC0D2c', '/dev/snd/pcmC0D0c', '/dev/snd/pcmC0D0p', '/dev/snd/controlC0', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=726e9457-64eb-4ea3-9304-30bf6c37b9de InstallationDate: Installed on 2016-08-25 (788 days ago) InstallationMedia: It IwConfig: lo no wireless extensions. enx00e112002c6f no wireless extensions. eno1 no wireless extensions.
