Hello,
I'm having a problem with freezes on shutdown and reboot. After a while kernel reports
INFO: task shutdown:1 blocked for more than 122 seconds.
and after another while it performs actual action (turns off or reboots).
I tested a behaviour on 3 different kernels:
linux-5.1.5.arch1-2 - freezes on shutdown/reboot
linux-zen-5.1.5.zen1-2 - freezes on shutdown/reboot
linux-lts-4.19.46-1 - works fine
I used nvidia-dkms because it gave me flexibility to switch between tested kernels more easily and using regular nvidia/linux nvidia-lts/linux-lts is annoying because any version mismatching on pacman mirrors will prevent xorg from running.
For the record - problem affects them as well.
What should I do next? systemd verbose log didn't give much, the same goes for dmesg. What more data should I gather and how? Where should I report this? Or maybe problem is easy to solve and I messed something up?
Thank you kindly for responses.

Post a complete
sudo journalctl -b-1
after rebooting from reproduction of the issue. In general a bit more information on your setup would be nice, like what kind of session you are booting into and which services are started, there isn't really an indication that this is indeed an issue with any relevance to the nvidia driver.

When I published this post I was pretty sure it wasn't a gdm/gnome 3/xorg session problem because I managed to freeze system on shutdown with gdm disabled. Now I cannot reproduce this issue without xorg so for now conclusion must be that gdm/gnome 3/xorg is somehow at fault.
LTS kernel seems to shutdown/reboot seamlessly. I can provide those logs for comparison as well if needed.
Shutdown frozen for a while:
journalctl -b for vanilla kernel with gdm enabled
shutdown debug script for vanilla kernel with gdm enabled
Everything fine:
journalctl -b for vanilla kernel with gdm disabled
shutdown debug script for vanilla kernel with gdm disabled
During sessions with gdm I logged in into DE and during non-graphical sessions I just logged into tty and run reboot command.

Bumping up. Does anyone have any comments on this? Any suggestions where should I report this? Gnome, xorg, linux bugtracker? Nvidia? Thanks

Did you actually ever try w/o the nvidia modules to isolate them as culprit?
Otherwise just https://bbs.archlinux.org/viewtopic.php?id=244699 ?
Also please don't empty post (bump), see the forum rules.
