[SOLVED] Network cards not detected after system upgrade

I wanted to check the status of wake on lan, so I installed ethtool, with system upgrade:

$ pacman -Syu ethtool

This was on a ThinkPad X250 with a new Arch install from about 2 weeks ago, and now:

$ uname -a
Linux cube 4.9.11-1-ARCH #1 SMP PREEMPT Sun Feb 19 13:45:52 UTC 2017 x86_64 GNU/Linux

After the upgrade I rebooted, and both ethernet and wireless controllers were missing:

$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Following the wiki I tried to check if the corresponding modules were loaded, but could not find them:

$ lspci -v 2>&1
lspci: Unable to load libkmod resources: error -12
...
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (3) I218-LM (rev 03)

I am looking into `lspci: Unable to load libkmod resources: error -12`, but I am kind of stuck.

Re: [SOLVED] Network cards not detected after system upgrade

Was your /boot mounted during the upgrade ?

please post pacman -Q linux and uname -a .

Re: [SOLVED] Network cards not detected after system upgrade

Your running kernel doesn't match the installed kernel, so you will not be able to load modules.  I'm not sure why it wouldn't have already been loaded at boot, but a reboot should suffice.

I already rebooted several time and still same issue.

Re: [SOLVED] Network cards not detected after system upgrade

Then Lone_Wolfs answer (which came in as I was writing mine) is likely on target.

uname -a is already in the initial post.

$ uname -a
Linux cube 4.9.11-1-ARCH #1 SMP PREEMPT Sun Feb 19 13:45:52 UTC 2017 x86_64 GNU/Linux
$ pacman -Q linux
linux 4.10.1-1

Re: [SOLVED] Network cards not detected after system upgrade

To give you a little more info about my system, I am using EFI systemd-boot.

I tried now to upgrade the kernel:

$pacman -S linux
warning: linux-4.10.1-1 is up to date -- reinstalling
resolving dependencies...
looking for conflicting packages...

Packages (1) linux-4.10.1-1

Total installed size:   79.90 MiB
Net Upgrade Size:        0.00 MiB

:: Proceed with installation? [Y/n]  

And I see the images in /boot beeing updated:

$ ls -la /boot
total 32784
drwxr-xr-x  2 root root     4096 Mar 12 19:54 .
drwxr-xr-x 17 root root     4096 Mar  7 20:35 ..
-rw-r--r--  1 root root 22634967 Mar 12 19:54 initramfs-linux-fallback.img
-rw-r--r--  1 root root  5958508 Mar 12 19:54 initramfs-linux.img
-rw-r--r--  1 root root  4962064 Feb 26 23:11 vmlinuz-linux

The thing is that my EFI System Partition(sda1) is not mounted.
And I am not able to mount it anymore:

$ lsblk /dev/sda
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 238.5G  0 disk
├─sda1   8:1    0   512M  0 part
└─sda2   8:2    0   238G  0 part /

$ mount /dev/sda1 /boot
mount: unknown filesystem type 'vfat'

I guess I should have mounted it a the beginning, before running: pacman -Syu.

Re: [SOLVED] Network cards not detected after system upgrade

Downgrade the linux package assuming it is still in the pacman cache

pacman -U /var/cache/pacman/pkg/linux-4.9.11-1-x86_64.pkg.tar.xz

If not use live media to boot then chroot in with /boot mounted and reinstall the kernel package
If you had to downgrade the kernel package mount /boot then install the linux package again
Edit /etc/fstab to add /boot
Umount /boot and clean files from mountpoint.
Edit:
spelling

That did it.

I managed to downgrade, mounted the ESP to /boot, and reinstalled the kernel.
I also added it in fstab and now ESP gets mounted at bootup.

Thank you very much!
