[SOLVED] Screen Flickering with Kernel but not with LTS Kernel

So a few releases back my screen started to flicker like crazy with the Linux Kernel.
Waited for a few updates but the problem still persists.

When using the LTS kernel everything works just fine.

Anybody an idea how to debug this further?

Relatively fresh arch install with the archinstaller and the gnome desktop.

The flickering looks like the screen is turning on and off randomly on my laptop.

Infos and Device:

- Starlabs MK IV (Intel N5030)
- Coreboot

https://wiki.archlinux.org/title/Intel_ … flickering ?
If not, does it also flicker on the console or in eg. an openbox X11 session?

Re: [SOLVED] Screen Flickering with Kernel but not with LTS Kernel

Current installed kernels

pacman -Q linux
linux 5.19.11.arch1-1

pacman -Q linux-lts
linux-lts 5.15.70-1

I have tested to start with the kernel parameter i915.enable_psr=0 with the NON LTS kernel and there was no difference.
Still flickering.


cat /boot/loader/entries/2022-08-28_10-16-02_linux.conf 
# Created by: archinstall
# Created on: 2022-08-28_10-16-02
title Arch Linux (linux)
linux /vmlinuz-linux
initrd /intel-ucode.img
initrd /initramfs-linux.img
options cryptdevice=PARTUUID=d7af32b0-427d-4222-bcb2-35491f7082eb:luksdev root=/dev/mapper/luksdev zswap.enabled=0 rootflags=subvol=@ rw intel_pstate=no_hwp rootfstype=btrfs i915.enable_psr=0

Also tried to use X11 with and without the parameter.
Still flicker.

The LTS kernel always works fine.

Edit1:

Booting without any kernel parameter changes and 5.19.4-arch1-1 works.
5.19.5-arch1-1 is okay too.
5.19.6-arch1-1 is okay.
5.19.7-arch1-1 is okay.

5.19.8-arch1-1 will introduce the issue.
