Intel I225-V R3 Ethernet Connection Issues

I would like to preface this question by stating that the OS I will be providing information from is Manjaro. I have posed a question on their forums regarding this issue and did not receive much in the way of suggestions or help. I have observed the exact behavior I will describe below when booting to live version of EndeavourOS, Manjaro, and the arch install disk. If this is not allowed I apologize.

After the most recent 6.5 kernel and linux-firmware updates I began to notice very inconsistent network performance. Local network performance could reach 1gb, but is spiky and fluctuates a great deal. Internet performance was what gave the issue away. Speed tests seem to be artificially capped at around 10Mbps, but I get peaks reaching my maximum bandwidth (300Mbps) at times. The first indication that this issue may have been introduced with either the kernel or linux-firmware was when I booted to an older arch install I had running kernel 6.0.8. Unfortunately, after booting back and forth to this install a couple of times the issue followed me there. I do have a journalctl dump from prior to the issue appearing though. I have booted into kernel 6.4, 6.5, and 6.6-rc1 all with the same poor network performance. Given how the problem eventually migrated to the arch install running kernel 6.0, I imagine the kernel and firmware packages may not be the issue at all.

I dual boot Windows 11 on this machine. Windows is installed on a separate drive, with fastboot and hibernation diabled. Any switching between Windows and Linux is done with a system shutdown in between. When in Windows, network performance is flawless. Internet speedtests show a steady connection speed capped at 300+Mbps. Iperf tests between this machine and another arch virtual machine maintain a steady connection state at 1Gbps. Results of these tests will be provided.

To give you a visual idea of the problem I am dealing with, please see this image. I believe the peak at the beginning of the test was near 300Mbps.

Further troubleshooting has involved the following:

  • Replace network cable

  • Replace network switch

  • Disable auto negotiation and set interface speed to 1000 Mbps. This has been set from the switch and through ethtool. I usually see a message in dmesg that manual configuration is not available.

  • Add pcie_port_pm=off pcie_aspm.policy=performance to my kernel boot parameters. I have ASPM disabled in the BIOS.

  • Disable ipv6 using kernel boot parameter ipv6.disable=1.

  • Remove DHCP reservation from router in case of any issue with different host name between Windows and Linux.

Journalctl outputs:

inxi -Fxz

The high retransmission rate in iperf in arch/Manjaro compared to the Windows run certainly seems to be an avenue to explore, I'm just not sure where to look. Any help or suggestions are really appreciated.

Re: Intel I225-V R3 Ethernet Connection Issues

This journal from my arch install tries to load iwlwifi-ty-a0-gf-ao-72.ucode: http://0x0.st/HJlq.txt

I considered bringing this issue up in my original post, since I've seen the journal spammed with iwlwifi errors in every OS I've tried to use since beginning to track this problem down but didn't want to muddy the water any further.

From my boot to the arch install disk, I had to disable wifi to not be spammed to death in the console with these errors. Disabling wifi (rfkill) did not help my original issue however. In manjaro, I followed the advice of another thread here, which I cannot find at the moment, suggesting to rename the iwlwifi-ty-a0-gf-a0-62 to 78 to see if that improved anything. I was still having the issue and think I ended up moving all of that series of firmware to the point it can't find any suitable firmware.

Re: Intel I225-V R3 Ethernet Connection Issues

Yes, but that's "Linux version 6.0.8-arch1-1" and your OP says "6.0.8-1_Arch the only working boot"
Or is it that that boot specifically workd while other runs - on this pretty dated kernel - do not?

Not having any firmware is rather not going to work.
The usual appraoch on suspected regressions is to move the newest versions (forcing the kernel to fall back to an older version) until the system stabilizes.
Replacing firmware versions isn't a good idea b/c the versions might be special-cased in the kernel module, the module might reject the FW b/c the name and internal version mismatch or you might blindly pick a version that's not even considered by your kernel (ie. the rename is inert)

Re: Intel I225-V R3 Ethernet Connection Issues

Sorry for the confusion. That is the install that initially did not have network issues, but after booting different distros a few times and going back, the problem became apparent in that install as well. Not sure how to explain that since it has not been updated.

I have hesitated to do a clean install of any distro simply because the process will take quite a while with the current network issues. I'll do a clean install of arch and report back.

Re: Intel I225-V R3 Ethernet Connection Issues

Oct 14 23:01:02 archlinux kernel: pci 0000:0f:00.0: [c0a9:2263] type 00 class 0x010802

Shows up in the good but not the bad boot and is apparently an nvme

Other than that there're way more iwlwifi firmware errors in the bad boot, thesy all show up after NM.
Assuming a race condition, what if you add iwlwifi to the initramfs and/or disable NM and only explicitly start it after you got yourself a cup of coffee?

Re: Intel I225-V R3 Ethernet Connection Issues

Seth, thanks for your help so far. Here is a clean install of arch, with kernel 6.5.8: http://0x0.st/HJ0_.txt. Still exhibiting the same issues.

I think this is the opposite of what you were suggesting, but I've blacklisted iwlwifi and regenerated initramfs. At the same time, I've disabled NetworkManager.service, and have been starting it after boot. Journal of the above changes: http://0x0.st/HJ0y.txt

Re: Intel I225-V R3 Ethernet Connection Issues

iwlwifi isn't in the last journal - the point of blacklisting it is to prevent it's automatic loading. You'll have to manually "modprobe iwlwifi" at some point w/ that setup.

Re: Intel I225-V R3 Ethernet Connection Issues

Latest journal. Booting with iwlwifi blacklisted and networkmanager disabled. Upon boot, start network manager and modprobe iwlwifi.

Re: Intel I225-V R3 Ethernet Connection Issues

iwlwifi isn't in that journal - the suggested order would be:
- boot
- coffee
- modprobe iwlwifi
- MORE COFFEE
- Start NM
- i dRiNk tOo mUcH CoFfEe
- in doubt explicitly connect the wifi from NM

However, if it happens w/ iwlwifi blacklisted/unavailable the NIC is irrelvant and the  iwlwifi/errors a red herring…
Since this happens across systems and even the one good "6.0.8-1_Arch" seems to have been a fluke: try some live distro like grml.org to check the behavior on a completely different SW stack.

Also make sure that fastboot is _still_ disabled (cause windows re-enables it w/ updates)
Also, going back to the OP, the iperfs between windows and arch are actually OK (there's a single short RT burst in one stint, but that's randomly "normal") - the massive problems are only shown in interaction between arch and manjaro - do you have an iperf arch/arch or grml/arch,arch/grml?

Re: Intel I225-V R3 Ethernet Connection Issues

Quick update: I think it is safe to say that the issues I was having were hardware related, not software. A few other issues started to present themselves and decided to try a different motherboard. New board has same intel 2.5Gb NIC and it works flawlessly. WiFi adapter is not intel on this board and I haven't tried it out but no error messages either. I appreciate the time you took to help me troubleshoot.
