Main reason of missed rx packets is ASPM issues. Helpful would be the output of "lspci -vv" to see whether the ASPM L1 sub-states are enabled.
What you can also try: - Change ASPM settings in BIOS - Comment out the following in rtl_hw_start_8168h_1: rtl_hw_aspm_clkreq_enable(tp, true); - Play with rx interrupt coalescing (see ethtool -C) I also have a system with RTL8168h and don't face the decribed issue. So it seems to be system-dependent. Appreciated would be a git bisect between last known good and current version. As mentioned before there have been quite some changes to r8169, and manually reverting some of them + testing would be a cumbersome work. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
