After updating to kernel 6.2.x, my Thinkpad P16s (from 2022) is now stuck when booting with 6.2.8 or 6.2.9. I have to use kernel 6.1.14 to keep it functional.
The behavior looks like the one described in bug 2182684 - but on a much more recent hardware and, obviously, the solution is not the same.
In journalctl, when i compare outputs from kernel 6.2.9 with (working) 6.1.14, i see that nouveau fails to start.
Reproducible: Always
Steps to Reproduce:
1. On my thinkpad, i use a pretty standard Fedora 37 installation - graphical configuration is the default
2. Update to kernel 6.2.x (i noticed it starting with 6.2.8, confirmed in 6.2.9)
3. Simply boot.
Actual Results:
Graphical interface never shows up.
I cannot access any commandline either (but that may very well because i'm new to fedora).
Expected Results:
Normal start of display manager.
For context : I'm new to Fedora, i chose this distro to put on a professional PC to get some stability and to be able to share with less linux-loving colleagues. I'm used to Archlinux for my personal projects.
Being on a professional PC, i have limited time to investigate. Do not expect instant responses.
Edit : I found an answer in https://discussion.fedoraproject.org/t/latest-6-2-kernel-prevent-gdm-session-to-start/80522
So I suppose this could be classified as an upstream bug.
However, my computer has also the i915 possibility - i would have expected the Intel driver to be used as a fallback. But, this might be a bit off-topic here...
