Hello,
it seems I have to reload the kernel module r8169 after hibernate.
Can anybody tell how I can trigger such a script?
Thanks
Rainer

It may work in the same way I sometimes have to “reset” my trackpad after the first (or occasionally not the first, but a subsequent) sleep or hibernate cycle:
sudo modprobe -r psmouse && sudo modprobe -a psmouse
(Not sure the -a is needed).
Is that module actually called r8169? … if so try substituting that for my psmouse example. also, this might well be kernel dependent as my above example doesn’t work on some HWE kernels.
Which are you using? mhwd-kernel -li

How did you come to that conclusion ?
Have you synced the linuxXX-r8168 package to your system ?
If yes - then uninstall - and reboot - then recheck …

The network is gone after the system comes out of hibernate, the issue is not there if the system just suspends to RAM.
sudo systemctl restart systemd-networkd
does not resolve the issue, but
sudo modprobe -r r8169; sudo modprobe r8169
does. It could be that the kernel module is not the root cause though.

@BG405: That part I understand, but I don’t know where to add the script that it gets executed automatically, when resuming from hibernate.
Unfortunately
$ cat /etc/systemd/system/fix-r8169.service

doesn’t seem to work (even though I enabled the service). I am not sure if a hibernate.target exists in Manjaro though…
That is because the default is NetworkManager.
Thanks for the hint.
Unfortunately
sudo systemctl restart NetworkManager.service
does not help either.
Not it was not installed.

Unfortunately, that does not solve the problem. Manually unloading and reloading r8169 after hibernate works, and the network is coming back after a short moment.
With the systemd service though neither the network is coming back nor does it reboot properly anymore:

Any idea or hint what could go wrong is welcome.
Check systemctl status fix-r8169.service after systemctl hibernate to see what it’s doing, or any messages.
Debugging the issue becomes more troublesome, since it seems that it is somehow intermittent ( I apologize for the poor prompt). If I interpret the output correctly, modprobe -r r8189 hangs in these situations:

Hmmm. I have no idea why it gets stuck. I guess the next thing I’d try is putting both commands in a script and just run that from ExecStart instead of using ExecStartPre.

I upgraded to
Linux smart 6.9.5-1-MANJARO #1 SMP PREEMPT_DYNAMIC Wed Jun 19 19:07:41 UTC 2024 x86_64 GNU/Linux
but the problem persists.
Also
~ cat /usr/local/sbin/reload-r8169.sh ✔
#!/bin/sh
modprobe -r r8169
modprobe r8169
~
and calling this from ExecStart does not change anything.
When I call modprobe -r r8169 and modprobe r8169 manually from a root console, that works reliably.
With the systemd script, I saw a hang after the second hibernate cycle.
I am wondering if that thread should move to Support → Kernel. If yes, who can do this?
Done. I also added the “network” tag for Forum reference purposes.
I’m currently looking into how to set this as a cron job. 
EDIT:
I did find this on Stack Exchange (courtesy of a mate who has better search-fu than I). I’m reading through it but maybe it will help.
