I've just updated to kernel 6.8.0-51, but it suffers from the same
issue. I'm attaching full boot logs from journalctl -b.

Title:
Ubuntu 22.04 fails to start after kernel update to 6.8.0-50
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello, I've recently (2024-12-24) updated the kernel in my Ubuntu
22.04 from 6.8.0-49 to 6.8.0-50, but it doesn't work. I can still
successfully boot 6.8.0-49 kernel. I'm using Lenovo Thinkpad L15 Gen 2
with AMD Ryzen 5850U.
As far as I noticed in boot logs from previous boot (journalctl -b
-1), there is some problem with X.org:

When booting 6.8.0-49 (the one that works fine), I see it uses /dev/dri/card1 instead (extract from logs attached as kernel-6.8.0-49-journalctl-boot-logs-ok.txt).
I'm also attaching:
- cat /proc/version_signature > version.log (from the working kernel 6.8.0-49)
- sudo lspci -vnvn > lspci-vnvn.log (from the working kernel 6.8.0-49)
- apt-updated-packages.txt - a list of updated packages
- kernel-6.8.0-50-journalctl-boot-logs-issue.txt - extract from logs from journalctl -b -1 (boot attempt using problematic kernel 6.8.0-50)
- kernel-6.8.0-49-journalctl-boot-logs-ok.txt - extract from logs from journalctl -b -0 (booting working kernel 6.8.0-49)
How can I make kernel 6.8.0-50 work?
BR,
Adrian
