Kernel Modules Failure at Startup

Hello,

After I updated my laptop with pacman -Syu and obtained the latest kernel : 4.15.8-1 I got an error on startup :

Failed to start Load Kernel Modules.

And then it doesn't start lxde.

However on tty2 I managed to rollback to : 4.15.13-2
This immediately launches my desktop environment on tty1

Here the journalctl -b when the problem occured

The dmesg :
https://pastebin.com/7jGwV20G

I saw that in the dmesg on the first lines it says that it loaded my kernel version before my upgrade : Linux version 4.15.3-2-ARCH
But I then checked the pacman log where you can see on line 9 :

[2018-03-13 17:10] [ALPM] upgraded linux (4.15.3-2 -> 4.15.8-1)

The pacman.log of today :

So my guess is something went wrong during the update process, but I have no idea what... ?

Thank you for reading me

Re: Kernel Modules Failure at Startup

Most likely explanation is that you didn't have your boot partition mounted when you updated. It's also possible your bootloader is looking at the wrong place.

Re: Kernel Modules Failure at Startup

Thank you, you were right.
The problem was that for some reason when I updated once, boot partition wasn't mounted so mkinitcpio copyed the file in the directory but not on the partition like it should. This had the effect to fail all the future mount attempts on /boot.
So from that I had to rm * my /boot mount correctly my esp and could update easily.
Wasn't easy to find out but I did it

When I installed arch 2 years ago I followed every step carefully, but today I don't remember which method I chose to mount /boot

Mount tells me this :

systemd-1 on /boot type autofs (rw,relatime,fd=35,pgrp=1,timeout=120,minproto=5,maxproto=5,direct,pipe_ino=2804)
