Problem after latest update on Testing / mkinitcpio

Hi,

This morning, I’ve updated my system with sudo pacman -Syyu, went to prepare myself a coffee and then rebooted without watching the result of the update, my mistake. Upon many reboot, I’m stuck with my motherboard logo. I can access grub and tried to fallback to 5.4 with no luck and the same problem.

After swapping GPU, fiddling with the bios and many reboot, broken update came to my mind.

I booted on a live USB with no problem and checked my pacman.log. Here it is :

So, after searching the forum, I did try to repair the update

manjaro-chroot -a
pacman -Syyu

mkinitcpio installed but still with the same error message

I’ve tried mkinitcpio -P but it spurts me the same error.
And now pacman -Syyu tells me there’s nothing to do anymore
I’ve tried reinstalling the kernel with mhwd-kernel -i linux58 but it tells me no target specified while chrooted to my broken installation.

I’m lost, never had any problem while updating Manjaro and I surely appreciate some help sorting this out and some explaining of what I did wrong to avoid this in the future.

For info fdisk -l

After you have updated the system to latest mkinitcpio 28-1.0 you can fix your system with:

$ sudo mv /boot/vmlinuz-linux54 /boot/vmlinuz-5.4-x86_64
$ sudo mv /boot/vmlinuz-linux58 /boot/vmlinuz-5.8-x86_64
$ sudo mkinitcpio -P && sudo update-grub
