Two additional data points: 1) When I boot the "broken" computer -- i.e. the one that gets rx misses under Linux -- into Windows, Windows can drive the Ethernet chip at full wire speed; I get 500mbps to a WAN host over TCP. I believe this suggests it is not a problem with the BIOS.
2) I actually have two of the broken systems (I bought two identical computers) -- they both show the same ethernet receive problem. I believe this suggests it's a software problem and not a hardware problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1880076/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
