XPS 9530 not powering off on 6.7.2-arch1-1

I am encountering a new problem on my xps 9530 running 6.7.2-arch1-1.
The system doesn't power off or reboot. Target shutdown is reached and the screen turns off, but keyboard backlight and fans stays on, indicating that the system is hanging somewhere instead of powering off. In the log I can't identify the problem. I would appreciate if anyone can point me towards a direction to narrow down the issue.

here is the log of my last boot from poweroff command until stalling

UPDATE: i am running wayland - the issue was somehow related to lightdm and switching to sddm resolved my issue

There's 6.7.3 now, you should probably try that first.

Re: XPS 9530 not powering off on 6.7.2-arch1-1

Unfortunately the problem persists in 6.7.3
It occurs 100% of the time when trying to reboot and ~90% of the time when trying to shutdown.
Here is an additional log of a reboot attempt: https://pastebin.com/rpyDcsmK
Logs from successful and failed poweroff attempts look identical to me.

Is there any other way to narrow down what might be happening?

Re: XPS 9530 not powering off on 6.7.2-arch1-1

From the log everything shutdown related works absolutely fine until the last bit that isn't even getting logged anymore. You probably would need to bisect this to find out the actual root cause.

FWIW something that can well have a consequence here is the kms hook in mkinitcpio including modules/firmware for everything especially also nouveau related, so if you have an nvidia graphics in there that you're driving via nouveau, maybe try and remove the kms hook from mkinitcpio and regenerating your initramfs.

Thanks for the input. My nvidia card is disabled and I am only running Intel graphics with i915.
HOOKS=(base udev autodetect keyboard keymap modconf block filesystems fsck)

I now believe the issue might somehow be related to lightdm.
If i pkill lightdm in a running (wayland) session, it is restarted and from there I can reboot and shutdown with no issue.

Without understanding exactly what caused the issue with lightdm I have switched to sddm and everything is now resolved.
