[SOLVED]Updated to newest kernel, now I can't boot

Hi,
I just updated to the newest 4.9.6-1 Arch kernel and now my system can't boot. As soon as I power it up I get the message

Failed to execute /init (error -2)
Kernel panic - not syncing: no working init found. Try passing init= option to the kernel. See Linux Documentation/init.txt for guidance.

I upgraded the system with pacman -Syu and systemd and linux were updated. I also ran mkinitcpio -p linux before rebooting, and now I can't boot anymore.

My loader entry for systemd is

title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options root=PARTUUID=<my root partition UUID> rw amd_iommu=on iommu=noagp

So if somebody could point me to a solution, I would be very grateful

Edit 1: Downgrading the kernel didn't fix it. So it seems like the kernel version doesn't really matter
Solution: Reinstalling with

pacstrap /mnt base 

did fix the issue

Re: [SOLVED]Updated to newest kernel, now I can't boot

How did you install Arch initially? Those aren't standard Arch paths.

I installed it manually with a live usb.
How are those not standard paths? They're explained like this on the systemd-boot wiki page. I just followed the installation guide on the wiki.

Re: [SOLVED]Updated to newest kernel, now I can't boot

I'm having the same issue as OP, ran update a day or two ago and can't boot with the same errors regarding failing to execute init. i tried passing init=/usr/lib/systemd/systemd and init=/usr/bin/bash with no results.

Try rebuilding the initramfs from a live media.

Already tried. No luck with that either

same problem with system boot-mate, and xfce with grub, booting up to the point and remains there for hours, for I did downgrade.

How can I do this? Is there a command I run on the live media?

Assuming you have not deleted the old kernel from your pacman cache: https://wiki.archlinux.org/index.php/Do … the_kernel

Unfortunately the cache seems to have been deleted. Is there a way, I can just download the kernel and headers from a source or something?

You could check for a previous kernel version here: https://wiki.archlinux.org/index.php/Arch_Linux_Archive

Did you actually deleted the cache?
I don't think that it can magically disappear by itself...

Well, i didn't even know this existed. So I could've deleted it by accident, but in the directory described in the wiki, there's just the kernel version I'm currently running.

Downgrading to this archive version didn't fix it. but the kernel version has changed on the panic screen
