[Ethernet] Automatic module loading with systemd is not working!

My Ethernet driver module is not loaded by kernel automatically.

> lspci -v

	Subsystem: Realtek Semiconductor Co., Ltd. Device 0123
	Physical Slot: 32
	Flags: bus master, fast devsel, latency 0, IRQ 16
	I/O ports at e800 [size=256]

But when I try and load it manually it works I am connected to the network.

sudo modprobe -v r8169

But it goes back to not working when I restart the computer. So I tried to use [PRE]systemd[/PRE] to automatically load the model every time the computer starts:

> cat /etc/modules-load.d/ethernet-r8169.conf
# Load Ethernet Module r8169 at boot
r8169

> sudo systemctl status systemd-modules-load.service

Notice: journal has been rotated since unit was started, output may be incomplete.

But it does not work; I still have to run [PRE]sudo modprobe -v r8169[/PRE].

What seems to be the issue?

Re: [Ethernet] Automatic module loading with systemd is not working!

Those logs suggest the module IS loaded at boot, but there's a simple way to verify that .

Once booted and logged in , execute

$ lsmod | grep r8169

If that outputs anything, the module is loaded.
Incase it's loaded but you don't have internet access something else goes wrong.

Post full dmesg and/or journal output.

Re: [Ethernet] Automatic module loading with systemd is not working!

There is nothing about network devices in dmesg.
I do notice errors related to sdc / ata4.00  . If you do have a sdc drive it has problems .

There is hardware in this system I haven't seen in a long time (like  a parallel port) .

Please post lspci -knn and ip link just after booting .

r8169 isn't automatically loaded because it only generically can drive that device, but doesn't fit the vendor/model ID.
Not sure why systemd wouldn't load the module at all, though.

Re: [Ethernet] Automatic module loading with systemd is not working!

If you've installed r8168{-lts} that contains a blacklist for r8169 and you probably want to remove those packages if you have them installed.

Re: [Ethernet] Automatic module loading with systemd is not working!

https://wiki.archlinux.org/title/SMART

No GUI, none needed.
Post "smartctl -a /dev/sdc" for a general oversight and see the wiki on how the daemon can send you mails or a desktop notification if there're issues.

Yes! Windows 10.

See the 3rd link below. This *can* also be the cause for the ata error.

Other than that, please see what V1del posted about r8168 and myself about your device actually requiring r8101 rather than 8169

Re: [Ethernet] Automatic module loading with systemd is not working!

Looks like this is a known problem:

Description:
No ethernet after suspend. Reseting NetworkManager did not work. It seems to be a problem with the kernel module.

To work around the problem, I removed the package and build r8168-dkms from AUR (https://aur.archlinux.org/packages/r8168-dkms/). Now the problem seems to be gone.


What worked:

Uninstalling r8169

yay -R r8169

Installing r8168-dkms

yay -S r8168-dkms

Why the driver for r8168 works for r8169 befuddles me. Hope it's not an inefficient solution (because of wrong driver).

Re: [Ethernet] Automatic module loading with systemd is not working!

Because you actually have neither:

02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL810xE PCI Express Fast Ethernet controller [10ec:8136] (rev 05)

You're getting generic support out of the other realtek drivers and unless this is a custom (zen/hardened) kernel, you also don't need the dkms version of r8168 (there's just no package for r8101 in the repos)

Re: [Ethernet] Automatic module loading with systemd is not working!

A search for 10ec:8136 and linux lead me to linux-hardware.org[1] which indicates that controller is supported by the r8169 kernel module .

$ modinfo r8169 | grep 8136
alias:          pci:v000010ECd00008136sv*sd*bc*sc*i*
$ 

It does seem the r8169 module is indeed the correct one and you don't need another driver .

Re: [Ethernet] Automatic module loading with systemd is not working!

There's nothing to compile, he just linked a bunch of hw dbase entries to make his point.

yay -R r8169

This did nothing at all, there's no such package.

yay -S r8168-dkms

At worst, this just go in the way. At "best", it replaced a previous r8168 installation (shadowing the device from the r8169 support) and failed the dkms build, so you accidentally removed the r8168 module.

pacman -Qs realtek
modinfo r8168
grep -r r8169 /etc/modprobe.d
