L1SubCtl1: PCI-PM_L1.2+ PCI-PM_L1.1+ ASPM_L1.2+ ASPM_L1.1- This means ASPM sub-state 1.2 is enabled. This should not be the case because the driver disables ASPM at probe time. Also there's no message in dmesg that ASPM can't be controlled by OS. So this might be a BIOS bug. This could also explain why there are not significantly more such reports, as RTL8168h is a very common chip version.
Regarding the iperf log it's not clear whether it's rx or tx direction. If client is the system we talk about, then it's tx direction. Please run iperf also with the "-R" option. Please also check with irq cialescing enabled: ethtool -C <if> rx-usecs 200 tx-usecs 200 -- 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
