Description of problem: Upon fresh install of Fedora 33 and even in the installer, I was unable to connect to a wired connection. It would also stall the boot process as the NetworkManager would time out attempting to establish a connection. Following this guide (https://tuxbyte.com/how-to-get-your-realtek-rtl8111rtl8168-working-updated-guide/) I was able to solve the problem. Apparently this issue goes back to 2011. My steps to solve the problem were slightly different to the guide so I'll post my steps here: 1. Blacklist r8169 drivers by running "# sh -c 'echo blacklist r8169 >> /etc/modprobe.d/blacklist.conf'". This seems to be a crucial step since r8169 seems to prevent the ethernet controller from working correctly. 2. # dnf install gcc make kernel-headers kernel-devel dkms 3. Download and extract the r8168 driver found here (https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software) 4. Install drivers by executing 'autorun.sh' 5. After installing I was able to connect via ethernet I found a similar bug report which effected a slightly different ethernet controller (RTL8125) which can be found here (https://ask.fedoraproject.org/t/realtek-ethernet-not-working-on-32/8143). In this bug report they say the issue will be fixed in kernel 5.9 however I'm unsure if there is a patch for RTL8111/8168/8411.
Well, you provide no details at all about the issue you're facing. At first attach a full dmesg. This would also give an idea which chip version you have. You have the Realtek NIC firmware installed on the system? What's the exact issue? Driver not loaded properly? Driver loaded and network brought up, but no link detected? What you refer to at the end is that RTL8125B support was added in kernel version 5.9. This should be completely unrelated, unless you have a RTL8125B.
My bad, I wasn't sure what info would be relevant. The issue is that when booting, NetworkManager-wait-online.service stalls the boot process and ultimately ends up failing. When logged in it constantly tries to connect to the network via ethernet but stalls at "Setting network address" then disconnects and tries to connect again endlessly. From what I read this seems to be caused by r8169 drivers causing issues for RTL8168 devices. I believe blacklisting the r8169 drivers solves the issue but I also installed the latest r8168 drivers from realtek's website. I believe the issue is the driver is not being loaded properly. This issue is present during a fresh install and in the live usb installation. I don't have Realtek NIC firmware installed. And yes you're right, the RTL8125B is unrelated. I was wondering if maybe it was related in some way since the user on the thread seems to have a very similar issue. Also worth mentioning is that this is for Fedora 33 (KDE spin) which comes with kernel 5.8. Since fixing the issue and updating the system I am now on kernel 5.9.

RTL8168 family consists of ~ 50 chip versions. Rev 0c (RTL8168g) typically makes no problems and runs rocksolid. However for other chip versions we've seen that there are buggy BIOSes out there. What's needed is a full dmesg with the r8169 driver. And especially NetworkManager also sometimes has bugs, therefore for such tests it can make sense to configure the network manually. If you don't have the firmware installed, then do so, as it's meant to solve compatibility issues. Then provide the "ethtool -i <if>" output to verify that the firmware is loaded. You could also test with latest linux-next, you can get it from kernel.org git.
It seems others with the same board don't face the problem, see e.g. here: http://linux-hardware.org/index.php?probe=c355efc65f&log=dmesg One difference is that they use boot command line parameter: amd_iommu=on You could re-test with this parameter set.
This is not a DKMS issue anyway, the driver where you report issue is in the kernel. Reassigning component.
I unblacklisted r8169 drivers then restarted the system. I can confirm that the issue still exists on kernel 5.9. I tried using the boot command line parameter: amd_iommu=on and it didn't make a difference. Here's the dmesg log where r8169 drivers are attempted to be loaded but fails: https://paste.centos.org/view/5d700a3a Also by Realtek NIC software do you mean the drivers found here (https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software)? In that case that is what solves the issue. Here is ethtool after the proper drivers are installed: > driver: r8168 > version: 8.048.03-NAPI > firmware-version: > expansion-rom-version: > bus-info: 0000:04:00.0 > supports-statistics: yes > supports-test: no > supports-eeprom-access: no > supports-register-dump: yes > supports-priv-flags: no I will later test with latest kernel.
Good news, r8169 driver seems to be able to handle r8168g in kernel 5.10.6. $ ethtool -i enp4s0 > driver: r8169 > version: 5.10.6-200.fc33.x86_64 > firmware-version: rtl8168g-2_0.0.1 02/06/13 > expansion-rom-version: > bus-info: 0000:04:00.0 > supports-statistics: yes > supports-test: no > supports-eeprom-access: no > supports-register-dump: yes > supports-priv-flags: no This kernel is in the updates channel so I guess this issue is mostly resolved. However it does pose a problem when installing Fedora 33 as I believe the installation media comes packaged with kernel 5.8.

Hard to tell what may have caused the issue based on diff between 5.9 and 5.10. Especially as I can't reproduce the issue on my system with the same chip version. Something board/BIOS-specific may be involved. r8168 vendor driver has quite some undocumented magic that may help to work around such board-specific issues.
This message is a reminder that Fedora 33 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 33 on 2021-11-30. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '33'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 33 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 33 changed to end-of-life (EOL) status on 2021-11-30. Fedora 33 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
