[SOLVED] Blackscreen after upgrade via chroot. kernel 6.12.30-1

Sorry, missed your previous post.

Attempt to revert with pacman -U 6.15.3

This is not going to work.
"-U" takes a file or url as argument, you can

pacman -U https://archive.archlinux.org/packages/l/linux/linux-6.15.3.arch1-1-x86_64.pkg.tar.zst

From the screenshots you're not booting the kernel that's installed so yes, you either forgot to mount the boot partition or are mounting a spurious boot partition.
Your "old fstab" cannot be the reason for that if you followed https://bbs.archlinux.org/viewtopic.php … 1#p2273241

I also do grub-mkconfig, which I assume is a missing step that causes the black screen. This one is wrong?

Likely. Depends on where and under what conditions you did this.
Stop. Flailing. Around!
You're creating a moving target that will be impossible to hit.

On the failing boot, from the rescue shell, run

lsblk -f; cat /proc/cmdline

and post the output so we know where we're at now.
Don't do anything else!

I do write pacman -U 6.15.3 just to simplify the writing.
I try to tackle all at once, but it all backfires.
So sorry, sir, I am not separating the problem properly. Actually, now I was able to boot properly, but still have issues https://wiki.archlinux.org/title/KDE#Plasma as my ssdm.

Post an updated journal and at least the outputs of

uname -a; pacman -Q linux linux-lts

Arch Linux
