[SOLVED] Modprobe non-functional. Multiple programs failing after f...

Update: See below...
I recently rebooted after a pacman -Syu.
Since doing this I can't connect to a network (so no full logs sorry). Or start X

The fatal error in X is

open card /dev/dri/card0 no such file or directory
Screen 0 deleted because of no matching configuration session
...
Screen found, but none have a usable configuration

If I try to connect to a network I find that only the loopback (lo) device is visible (from ip link)

lspci -v gives network controllers Qualcomm ... with no kernal driver field (as I think I'd expect to be there?)

If I try to load the alx module manually I get:

 modprobe: FATAL: Module Alx no found in directory /lib/modules/4.17.2-1-ARCH 

However the alx module (I think) is here under /lib/modules/4.17.3-1-ARCH/kernal/drivers/net/ethernet/atheros/alx

So I think modprobe is looking in the wrong place (It is thinking we are a version beind). Normally I would try and fix this by reinstalling linux or something but without finctioning ethernet devices that's not happening.

So... Any ideas?

[Update]

The problem seems to be that the systemd-modules-load is failing

Error is

Failed to lookup ailias 'crypto_user': Function not implimented

Normally I would reinstall the kernel but I don't have network access.

Trying to run mkinitcpio gives

/lib/modules/4.17.2-1-ARCH is not a valid kernal module directory.

How do I get it to use 4.17.3-1-ARCH (the installed kernel)?

For Clarity:
Running Kernal (uname -r) is 4.17.2-1-ARCH
Installed Kernal (pacman -Q linux) is 4.17.3-1-ARCH
This is the source of the issue.

Non-matching, hence why I'm trying to update the kernel

You didn't have your /boot partition mounted when doing the update. As you are unlikely to be able to mount it due to the same problem, you should use a live usb properly mount all relevant partitions (including /boot , however you might want to remove the incorrect /boot directory on your root partition before doing so), chroot in and update your system. Properly define your /boot partition in your fstab so you don't have to do this again.

The uuid was miscopied into the fstab. I can mount /boot just fine(don't ask why this piece of hardware is working above all else). Problem is I left my live boot usb at home (I have a spare but it looks like I forgot to finish the setup of it). Is there a way to replace the kernal (since it's apparently installed) from the system?

Downgrade to 4.17.2-1 from the package cache so the modules match then mount /boot then upgrade the kernel then unmount /boot and clean anything left in /boot.
