[SOLVED] Ethernet interface gone after kernel update

Hello,

Normally I'm not the only having a given issue after kernel update, however, this time it seems so. After doing the latest kernel update yesterday, to version 4.11.9-1, my Ethernet adapter stopped working, or rather, it is not even found.

When I try to activate my network profile with netctl:

$ systemctl  status "netctl@eno1\\x2dEthernet.service"
● netctl@eno1\x2dEthernet.service - Networking for netctl profile eno1-Ethernet
   Loaded: loaded (/usr/lib/systemd/system/netctl@.service; static; vendor preset: disabled)
   Active: failed (Result: exit-code) since Mon 2017-07-10 22:47:58 CEST; 8s ago
     Docs: man:netctl.profile(5)
  Process: 10110 ExecStart=/usr/lib/network/network start eno1-Ethernet (code=exited, status=1/FAILURE)
 Main PID: 10110 (code=exited, status=1/FAILURE)

Jul 10 22:47:58 JohnMacbookPro network[10110]: Interface 'eno1' does not exist
Jul 10 22:47:58 JohnMacbookPro network[10110]: Failed to bring the network up for profile 'eno1-Ethernet'
Jul 10 22:47:58 JohnMacbookPro systemd[1]: netctl@eno1\x2dEthernet.service: Main process exited, code=exited, 
Jul 10 22:47:58 JohnMacbookPro systemd[1]: Failed to start Networking for netctl profile eno1-Ethernet.
Jul 10 22:47:58 JohnMacbookPro systemd[1]: netctl@eno1\x2dEthernet.service: Unit entered failed state.
Jul 10 22:47:58 JohnMacbookPro systemd[1]: netctl@eno1\x2dEthernet.service: Failed with result 'exit-code'.

I then tried to look into it with ip link, and it seems that my Ethernet not even is found (I have replaced with xx:xx:xx:xx:xx:xx).

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback xx:xx:xx:xx:xx:xx brd xx:xx:xx:xx:xx:xx
2: wlo1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
    link/ether xx:xx:xx:xx:xx:xx brd xx:xx:xx:xx:xx:xx
4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether xx:xx:xx:xx:xx:xx brd xx:xx:xx:xx:xx:xx
24: tun0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 100
    link/none 

As there doesn't seem to be other people to have the problem, is there something I miss? Eg. a kernel module not activated, because I don't know where to look.

Any help would be greatly appreciated.

Re: [SOLVED] Ethernet interface gone after kernel update

Are you sure you are running 4.11.9-1 ?  Does uname -a agree?

Re: [SOLVED] Ethernet interface gone after kernel update

When I check online I see the current version is 4.11.7

I have just used the following command to update the mirrors for fastest speed:

fetchmirrors --noconfirm -c DK

Is it because I use the danish mirrors I get a beta version?

Re: [SOLVED] Ethernet interface gone after kernel update

That's the ISO, not the current stable kernel in the repos.

Re: [SOLVED] Ethernet interface gone after kernel update

What module did the interface previously use?  What is the interface usb/pci with what vid:pid?  Are there any failed services such as systemd-modules-load.service?

Re: [SOLVED] Ethernet interface gone after kernel update

Thank you for the question loqs!

It used and use the kernel module r8169, and have the interface PCI.

Sorry, I have been so dumb, I didn't check whether the kernel module was loaded (I had forgotten that I used a custom module from AUR...). It all works now again after activating the module with:

modprobe r8169

Have a good day.
