[SOLVED]pacman update upgrades linux kernel, boot fails kernel modules

pyrole · 2022-07-14 19:11:33

I ran sudo pacman -Syu and it upgraded the linux kernel.
But the grub bootloader still tries to boot into the old kernel.
I have my 512 mb efi partition mounted on /boot/efi.
Pls tell me how to fix this thanks.

Also my arch is on other laptop and i am typing this output by hand so pls forgive if there are any small typos, I'll try my best to double check everything.

also the vmlinuz-linux in /boot/efi is the same version as that in /boot
....

So lemme tell you what all happened from the start.
Initially my uname -r showed the older kernel version when compared to my version of vmlinuz-linux in /boot
So i ran

sudo mount /dev/nvme0n1p1 /boot
sudo pacman -S linux
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

I picked up the above commands from other similar problem solutions.

seth · 2022-07-14 21:28:12

sudo mount /dev/nvme0n1p1 /boot

That should have been "sudo mount /dev/nvme0n1p1 /boot/efi"?
nvme0n1p1 is supposed to be /boot/efi and you're loading the kernel/booting from the root partition.

Initially my uname -r showed the older kernel version when compared to my version of vmlinuz-linux in /boot

Does it still?

1. But wasn't nvme0n1p1 already mounted on /boot/efi as shown in lsblk?
2. No now uname -r shows the latest kernel version same as vmlinuz
3. Also pls tell me how do I fix this mess I made and what all I should have done from the beginning itself

I wanted to check whether that was a typo.
If it wasn't and you augmented the /boot path of your root partition w/ the EFI partition this explains why you've a kernel there and also why the relevant kernel (in /boot - w/o mounting anything there!) wasn't updated.
The updated kernel went, falsely, into the EFI partition.

You can remove it and the initramfs' from /boot/efi.

Yes that wasn't a typo, also the nvme0n1p1 got unmounted as soon as i rebooted so now it is only mounted to /boot/efi

Can you kindly tell me the appropriate commands i need to run for each step?

What command for what step? Removing files???

Also, is there still an issue w/ the boot (since you're no longer booting a dated kernel)?

i mean yeah i deleted both the initramfs and vmlinuz form /boot/efi so i just wanted to confirm with you if thos exact files were supposed to be deleted.....

Also how do we fix the boot issue?

seth · 2022-07-14 21:56:46

Since you're no longer booting a dated kernel it's not clear whether and what that issue would be (see my previous post)

Please post the system journal for a failing boot, https://wiki.archlinux.org/title/System … al_to_view

Yes the kernel moduels still aren't getting loaded on boot.
I didn't quiet understand how to get the system journal on the link you provided : (
Also even if I get it idk how to share it with you, currently i am using a second laptop and the broken arch is on my first, it has only tty's working so how do i share the outputs?

First link below.

If you can boot the system (despite the error) and have network access, just post "sudo journalctl -b".
Also check "systemctl status systemd-modules-load" - I assume the only thing that fails is the nvidia module and this is actually just an extension of https://bbs.archlinux.org/viewtopic.php?id=278042 …

Ok so we can consider the nvidia fail to be redundant because I reinstalled my OS, so in this install I haven't touched the nvidia driver.
After the install I didn't do many changes, just few installations, lightdm, xfce4 and all which were working normally, the only problem arrised when i did pacman -Syu and I expected this problem because I had faced this in previous installation too but i forgot how i fixed it.

For sudo journalctl -b:
http://ix.io/44nP

Also I could not "boot" into the system, as in I was only able to access the tty nothing else.

systemctl status systemd-modules-load:
http://ix.io/44nR

Also since I messed quiet some shit up, i can easily reinstall my Arch and maybe you can guide me from there if that would be easier for you? What i mean is when i reinstall my problem is almost the same as in this post:
https://bbs.archlinux.org/viewtopic.php?id=270312
Except that i have an efi partition.....

But now the problem is something else i guess so just lemme know if you want me to reinstall a clean OS or try to fix this one.

Is this what you mean ?

Due to FS#74886/FS#74891, nvidia does not boot on Linux 5.18 on systems with Intel CPUs. Until this is fixed, a workaround is disabling the Indirect Branch Tracking CPU security feature by setting the ibt=off kernel parameter from the bootloader. This security feature is responsible for mitigating a class of exploit techniques, but is deemed safe as a temporary stopgap solution. You can alternatively try nvidia-open and continue using IBT.

If yes, which file has the ibt kernel parameter? Also after making that change do i run sudo grub-mkconfig -o /boot/grub/grub.cfg?

seth · 2022-07-14 22:59:22

The "kernel parameter" token in the wiki is a link. Do you think you want to click it?

Sir I did click the link and tried to understand it to my best of abilities..... Then i added ibt=off to the grub.cfg because that was what i understood then i did grub update.
Where did i go wrong?
