[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
Did some more testing and found some interesting results. I forgot to mention the reason for extra SSD is so that I could set up a dual boot with Windows 10 via GRUB. I have discovered it is Windows that is creating my problem. If I boot straight into Linux from power off I have no latency issues. However if I first boot into Windows, then restart into Linux the latency issue occurs. It is definitely related to ASPM as the Linux kernel pcie_aspm=off flag prevents the issue. I also tested a bunch of settings in the BIOS and the results (NOK means issue still occured): Boot -> Fast Boot -> Disabled - NOK Advanced -> Platform Misc Configuration -> PCI Express Native Power Management -> Disabled - OK Advanced -> Platform Misc Configuration -> Native ASPM -> Disabled - OK Advanced -> PCH Configuration -> ASPM Support -> Disabled - OK Advanced -> PCH Configuration -> ASPM Support -> Auto - NOK Advanced -> PCH Configuration -> ASPM Support -> L0s - OK Advanced -> PCH Configuration -> ASPM Support -> L1 - NOK Advanced -> PCH Configuration -> ASPM Support -> L0sL1 - OK I don't really understand much about ASPM and how OSes and BIOSes control it, but it seems with ASPM support set to auto or L1, then somehow after the system reboots from Windows some sort of state is left set which causes the latency. Possibly related to the L1 state. Anyway I am going to leave ASPM in BIOS set to L0sL1 so that ASPM is still used but whatever Windows is doing is reset by the BIOS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Expired Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
I think I ran into same the same problem. Only started happening recently when I added an extra SSD and re-arranged my SATA device ports. I also made some changes in the BIOS, the main one was disabling the CSM (compatibility support module) setting and forcing a UEFI boot. Basically I was having issues not being able to connect to Internet every so often and having to disable/enable the Ethernet port multiple times to reconnect. A ping to local device and 8.8.8.8 revealed widely varying ping times from sub ms to 1000 ms, which was not replicated on a different computer on same network. ethtool was also showing a large rx_missed count. I tried the kernel pcie_aspm=off flag and issue disappeared. My motherboard is a ASUS H81M-E and manual says the Ethernet chip is Realtek a RTL8111G. BIOS is the latest version from 2018. When I get some time I will try and see if one of the BIOS settings affects things. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Expired Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

It depends on your actual hardware.

I tried: echo 'performance' > /sys/module/pcie_aspm/parameters/policy This did not improve performance or reduce packet loss. I don't think it's right to give up and say "Well, this is a BIOS bug." The 18.04 kernel does not exhibit this problem, nor does Windows, but the 20.04 kernel does. It's the kernel's fault, even if the kernel's bad behavior was triggered by a bad BIOS. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

In addition you can try to set kernel command line parameter pcie_aspm=off. Or set pcie_aspm.policy=performance. In general it's a tradeoff: Older kernels didn't allow to enable ASPM at all, resulting in less battery life on notebooks. Newer kernels disable ASPM per default, but allow to re-enable it via sysfs. For this however they depend on proper BIOS support. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

One more data point. Using the ethtool command described in comment 16 (rx-usecs 200, tx-usecs 200) I see about a 10% improvement in bandwidth but still a large number of dropped incoming packets resulting in small TCP congestion windows (and thus a small fraction of the overall TCP goodput achieved by Windows on the same hardware). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

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.

[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

if we can compile a kernel directly from kernel.org we can revert some
of these commits and test which one is causing that issue. but i found
not yet a manual how to compile using mainline-sources directly.
config is (at least in 18.4) /boot/config-5.3.0-59-generic

[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
@jeremy Thanks for confirming. Is it possible to install 18.4 kernel (afair i used 5.3) in 20.4? If the problem is gone (i guess so) we have only compare 2 major versions. Are there any Patches from ubuntu on top of 5.3 (18.4) and 5.4 (20.4)? If not problem is in mainline source...is the above mainline-kernel untouched? How can i build mainle kernel (without ubuntu patches,but same config) from git.kernel.org? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.

[Kernel-packages] [Bug 1880076] Re: ubuntu 20.4 - retransmitts with r8169
I am having an almost identical issue with Ubuntu 20.04, kernel 5.4.0-40-generic. I believe it is related to the ethernet driver. I have two almost identical computers, both running 5.4.0-40. The bad one has the following driver: eth0: RTL8168h/8111h, 00:e4:4f:68:0e:77, XID 541, IRQ 126 On this computer, I see hundreds of increments to "rx_missed" every second while trying to do high-speed transfers to WAN hosts with high latency. Due to all the TCP segment losses, the TCP window never fully opens and bandwidth is poor (about 20 megabits on a 1gbps connection). Transfers on the same LAN happen at 1gbps, presumably because the latency is so low that the re-tx happens quickly. Sitting next to it, on the same LAN, is a "good" computer -- virtually identical except the Ethernet chipset. It is also running 5.4.0-40, but with a different driver: eth0: RTL8168evl/8111evl, 00:e0:4c:68:04:7d, XID 2c9, IRQ 126 On this good computer, I see no rx_missed increments even after hundreds of gigabytes of transfers. TCP happens at near wire speed even to WAN hosts. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1880076 Title: ubuntu 20.4 - retransmitts with r8169 Status in linux package in Ubuntu: Incomplete Bug description: Hi, i run some network-tests (iperf3) and noticed massive retransmitts in ubuntu 20.4 with kernel 5.4.0-29.
