[SOLVED] Latest installed kernel doesn't get properly updated

So for some reason the kernel under `/boot` and the modules under `/lib/modules` are the same version, but `uname -a` reports a different version, no matter how many reboots.

I've run `mkinitcpio -p linux-lts` several times and `grub-mkconfig -o /boot/grub/grub.cfg`, I've run `pacman -Syyu`. Here's the values:

$ uname -a
Linux eduan-t440p-arch 4.5.4-1-ARCH #1 SMP PREEMPT Wed May 11 22:21:28 CEST 2016 x86_64 GNU/Linux
$ ls /lib/modules
4.4.14-1-1lts/  extramodules-4.4-lts/
$ pacman -Q linux-lts
linux-lts 4.4.14-1

And I run `mkinitcpio -p linux-lts` and I can see in its output the proper kernel version, that gets loaded into `/boot`, and when I take a look at `grub-mkconfig -o /boot/grub/grub.cfg`'s output I can see that it's grabbing the just-generated kernel images.

But even still, when I reboot I have another kernel, and I've no idea where it's getting this kernel from or why this de-sync happened. I've uninstalled the `linux` and `linux-headers` packages...

The problem that this causes is that no modules are loaded, which means there's a super fast boot but no proper wifi drivers, screen drivers or useable Xorg.

Ask me for all the info that you need, just remember I can't copy-paste, I'll be typing everything manually from one screen to another.

So where is your bootloader finding that kernel?

Re: [SOLVED] Latest installed kernel doesn't get properly updated

That's exactly what I'm trying to figure out. I am not super familiarized with grub since I've always used LILO or Syslinux.

When I press tab at grub's menu what I get is:

.linux ../vmlinuz-linux root=/dev/mapper/main-root rw initrd=../initramfs-linux.img

Which I can right away tell is not right, since it's not the LTS version, but I don't know where I can change this, or where `.` and `..` are in this context...

Re: [SOLVED] Latest installed kernel doesn't get properly updated

I've checked `/boot/grub/grub.cfg`, searched for 'vmlinuz' and all the mentions I find are to '/boot/vmlinuz-linux-lts', so that's OK there...

Holy crap. `grub-install /dev/sda` fixed it. Jesus. So I can't just update the config, I also gotta install the new version...

Damn that was painful, sorry for this post, but externalizing and you asking the question I've been trying to answer helped out. Thanks dude.
