Thanks for the reply. Maybe I'm not correctly interpreting the reply referring to "a kernel issue like this requires kernel bisection" and "We can't do much if we don't have the hardware".
Why would the internet connectivity issues I'm seeing with Ubuntu 18.04 Server running the Intel onboard i219-v Ethernet adapter be a kernel issue? As I've stated multiple times already, this i219-v Ethernet adapter ran perfectly on CentOS Server 7.4 for over a week (and we know CentOS is much more conservation with the Linux kernels used in their distribution) before I removed CentOS 7.4 and decided I'd given Ubuntu Server 18.04 a try and see where Ubuntu is at as a Linux server distribution vs CentOS. Given my experience designing and building $B networks, this is not a hardware issue (very, very rare) and given CentOS Server 7.4 worked perfectly for everything expected of a server, including the network performance using this same i219-v Ethernet adaptor, it's most likely not a Linux kernel issue. There's something in the way Ubuntu Server 18.04 is configured to use this Intel i219-v onboard network adaptor hardware that's the root of the issue. It's probably a scenario that Ubuntu Server 18.04 had probably not seen before and was never verified with (given what I know and have observed with how software is tested these days. My vendors constantly use us as a testing platform, but that's a separate story). Again today, the network adaptor on the Ubuntu 18.04 server lost connectivity to the internet and I had to disconnect and then reconnect the wired Ethernet connnection to get the internet connection backup (simply, Network Manager service has to be stopped and then restarted, you can see it clearly in the logs I provided in a previous post). What is Ubuntu support/development saying here? That Ubuntu Server 18.04 can't execute basic internet connectivity on the i219-v Ethernet adaptor in a 100% stable manner? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1785171 Title: Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver keeps Dropping Internet Connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1785171/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
