Hi!
As the title says. After update screen stays black. No error message, nothing. I arch-chrooted and restored a snaphot, but I don’t know where to look for solution. Where should I start troubleshooting?
Thanks
I find it strange that if you restored from a snapshot that you still have the same issue. Have you tried rolling back using eos-shifttime
Sorry. My system works now, but if I run update, the problem comes back.
Could be a lot of things. Newer package, kernel etc?
I run the update again. It gives this error message:

EDIT: I’m using LTS kernel
Try this:
Change MODULES=(crc32c_intel) to MODULES=(crc32c) in /etc/mkinitcpio.conf file.
Then run mkinitcpio -P
Edit:
It’s probably a good idea to make a backup of the file first.
Do what @EOS has stated. See if that works. That module is now integrated into newer kernels.
That did not help. It does not give the error message anymore while building the image. But system fails to boot. Only black screen and little flashing.
Maybe you could arch-chroot off the live ISO and try to run an update and see what happens.
It updated some haskell packages, but nothing more.
Interesting. I run
pacman -Syu --ignore=linux,linux-headers,linux-lts
And now system works after update. Should I just wait that these packages get newer versions and try again then?
Have you checked if it boots on each kernel? Which one doesn’t it boot on if you update?
Edit: Sure you could wait for another kernel update and see.
You are missing linux-lts-headers
What is your old kernel version? What uname -r prints?

I don’t have linux-lts-headers 
You have a pretty old lts kernel:
linux-lts-6.12.41-1-x86_64.pkg.tar.zst 01-Aug-2025 20:54 138M
It might be better to update a little more frequently.
If you’ve managed without them so far, you can probably install them when the need arises. Or download and install the correct version from:
https://archive.archlinux.org/packages/l/linux-lts-headers/
A new lts kernel was released today. Try updating next time with sudo pacman -Syu linux-lts-headers
Yes, I did this and now system boots normally. Thank you ricklinux and EOS for your help!
