[SOLVED] Network interface enp2s0 no longer detected

Hello,

Yesterday after rebooting, right after Grub, systemd-fsck does its stuff (clearing blocks, etc...) then nothing.

After a quick research I've found that removing "quiet" from the Grub command line would allow more messages to be displayed, which was quite helpful.

This is in fact not a partition mounting problem, here is what I have:

...
[ OK ] Started Accounts Service.
[ TIME ] Time out waiting for device sys-subsytem-net-devices-enp2s0.device
[ DEPEND ] Dependency failed for dhcpcd on enp2s0.
[ OK ] Reached target Multi-User System.
[ OK ] Reached target Graphical Interface.

I obviously have a networking problem (and probably a "Graphical Interface" or Nvidia related thing problem), so I log in another console, and after doing ip link list, I only have the loopback listed, no enp2s0 or WiFi interface, for some reason they are no longer detected.

I've run the live version of Arch to mount and arch-chroot my partitions, not to mention my network interfaces are detected and I can upgrade things with pacman, I've tried to disable dhcpcd on enp2s0 to avoid the time out thing, and while I can say it does what it's supposed to do, it doesn't solve anything anyway since I'm still stuck at Reached target Graphical Interface. (and don't have any network access, to state the obvious).

I've even thought about a Kernel/Driver problem after an update, but I'm not sure, any idea or some log I can have a look at ?

Thank you for your time.

Re: [SOLVED] Network interface enp2s0 no longer detected

Your pacman log (since the last update) would be the first place to look. Also, please provide the relevant information about your network device.

What's the output of 'ip a'?

Re: [SOLVED] Network interface enp2s0 no longer detected

If I'm not mistaken the 'r8169' module should take care of your network card.

Is there anything in dmesg related to r8169?

How about

modprobe r8169
lsmod | grep r8169

Or better yet

lspci -v | grep -A20 "Ether"

Re: [SOLVED] Network interface enp2s0 no longer detected

You can happily ignore the warnings from the build of the fallback initrd.

What driver are you using for your wireless card? Should you have rebuilt it agianst the new kernel?

	Subsystem: Hewlett-Packard Company Device 2a9c
	Flags: bus master, fast devsel, latency 0, IRQ 18
	Memory at fbbff800 (64-bit, non-prefetchable) [size=2K]
	I/O ports at e800 [size=256]

and

modprobe r8169
lsmod | grep r8169

gives me nothing, which suggest I miss this module.

Then I tried to use the coordinates to find the driver.

find /sys | grep drivers.*02:00

In a normal situation, I would have something like /sys/bus/pci/drivers/r8169/0000:02:00.0
in response (for what understand), but I have nothing, I've checked in /sys/bus/pci/drivers/ and no r8169 so far, which seems to confirm the module is missing.

Concerning my Wireless card, honestly I don't know, I can't even recognize it in lspci, moreover I've not been using any wireless connection so far, only a RJ5 cable, that's why dhcpcd run for enp2s0 (Ethernet), I didn't explicitly build the module against the new kernel myself yet either.

Re: [SOLVED] Network interface enp2s0 no longer detected

I have this eithernet card of a different revision.  Most others who also have it say that r8169 works just fine, but I have to use r8168 on my machine.  There is an r8168 package in [community] that is built for the current kernel.  It is not a solution as to why your module won't load, but it might actually make the thing usable.

Also, since we are talking about modules not loading, have you done the basic santiy check of ensuring that your running kernel matches what pacman reports and the directory in /usr/lib/modules?

Do you mean /usr/lib/modules/3.9.7-1-ARCH/ ? Yes it exists apparently, with directories in it.

I tried using r8168 instead of r8969, after blacklisting the original and rebooting then modprobing this one, sadly it didn't do anything (but I still may have missed something).

Just in case, here's what pacman gives me about my current kernel version (pacman -Qi linux):

something goofed up with the nvidia kernel module too, which explains my graphical interface problem, I do have Kernel modules issues like I supposed first.

Also:

[    13.437] 	compiled for 4.0.2, module version = 1.0.0

Does it refer to the kernel version, or is it something else ?

Re: [SOLVED] Network interface enp2s0 no longer detected

You're still booting off of 3.9.6 according to your Xorg log which explains why modules aren't loaded (derp, they no longer exist). /boot not mounted for the upgrade? Failure to copy new kernel to the ESP?

Re: [SOLVED] Network interface enp2s0 no longer detected

Thank you !

/boot not mounted for the upgrade?

That was my problem !

In fact I had to reinstall the system something like one week ago (because of a HDD failure, of the hardware kind I mean...), I did one partition for /boot, one for /home, and one for the rest of the system (plus the swap indeed), during the initial system installation all of this was properly mounted so /boot had it's own partition and Grub was properly configured.

The problem is genfstab was not working so I had to handle /etc/fstab myself, I realised I goofed up with it first when only the partition for "/" was mounted, in consequence the whole system was running on this only partition (~30Go), I realized something was wrong after some game installs, there was no more space left (in my head /home was still on its own partition, with almost 1To), so I understood /home was not properly mounted, I corrected it, I managed to move my /home directory to the dedicated partition and everything was rolling well.

I stupidly let /boot like it was, meanwhile it was still booting on grub from the dedicated partition left by the initial system installation, and there was no trouble either since the kernel was still the same until two days ago.

It was totally stupid from me, thank you all of you for the help !
