[SOLVED] Dock Network Breaks On Resume

[theokonos]

Hello,

I'm having this strange issue where when I either un-dock and re-dock, or wake my laptop from sleep, my dock network adapter becomes disabled. WiFi interfaces are not impacted, and neither are other hardware dongles (USB Ethernet adapters, etc).

Restarting NetworkManager.service unfortunately does not resolve the issue either. So far my only working remedy is to reboot while docked, and then everything works normally.

System Info:
Laptop - ThinkPad X1 Extreme Gen2
Dock - ThinkPad Thunderbolt 3 Workstation Dock Gen2

Please answer the following question:

Is the LAN Adapter that breaks upon resume used in a virtual environment (or is Manjaro installed on bare metal)?

I would suggest making sure your dock's firmware is completely up to date before doing anything else.

If that does not improve things then testing 4 alternate kernels would be my next suggestion.

If that does not solve your problem then I would suggest you search the terms "mask tlp" and temporarily disable tlp via masking it. Tlp is required on a laptop, so it would be best to determine which setting (thunderbolt or your adapter) needs to be modified in tlp's configuration file. Do your own research on this as I do not use tlp.

The final option you are left with (if no other method works) is to write your own service to either disable your thunderbolt dock or your Ethernet adapter (or both) prior to suspending and reload them upon resume.

See my systemd thread for many working service examples:

Writing Systemd Service Units

I thought it would be great to have a central thread to compile information on systemd. Please feel free to post any examples of systemd units, or any other info relating to systemd on this thread. The forum contains many different types of systemd units. If you are looking for a specific type of unit, I have categorized some common types to make examples easier to locate: Networking: Network - WiFi: Intel iwlwifi - Suspend Service Atheros ath10k - Suspend Service Realtek rtl8812au- Suspe…

Intel I218-V Ethernet doesn't work after a suspension/powering on.

My bad I didn't see it. If it comes to this script, as far as I can see this is not the best solution, as it takes some time to load it up, although it works, so until there is not updated kernel with the fix here's my version. #/etc/systemd/system/network-restart.service #sudo systemctl enable network-restart.service #sudo systemctl start network-restart.service #sudo systemctl stop network-restart.service #sudo systemctl disable network-restart.service #systemctl status network-restart.servic…

Ethernet over thunderbolt freezes hibernation process

Until the issue is fixed in the kernel, the workaround is to disable some (or all) of your networking components prior to suspending. After resuming you re-enable them. This can all be accomplished automatically by writing a systemd service.

Thank you for the thorough response! Manjaro is installed on bare metal, so I'm dealing directly with the Thunderbolt dock. The firmware for the dock is also up to date .

As for the kernels, I've tried 5.4, 4.19, and 5.6 all with the same results.

Thanks for the top on tlp -- I'll have to research that and get back to you on my findings.

And if that doesn't work, thanks for the systemd references! I'll give those a try if it comes to it.

Thanks again!

[theokonos]

Hey so, good news!

I must have been doing something wrong when testing previously, because I tried out 5.6 today (5.6.11-1) and it fixed the issue. I can boot off-dock, go to sleep, disconnect, etc. and Manjaro re-activates the dock ethernet interface when I reconnect it as it should.

Thanks again for your help! At the least, I got a good intro to TLP. If you end up needing to point people down that line again, there's a good GTK interface for TLP in the AUR that may be helpful to people who are less familiar with it.

Cheers,
Theo

That is true, for those who prefer a GUI that is an easier way to familiarize yourself with tlp's settings.

I'm glad your issue has been resolved, perhaps a recent update fixed the issue.
