When I perform reboot, the laptop close session and them, turn off the display. After few seconds, the display turn on. So, shows the message: Systemd-udev .... and KDE starts normally.

What works:
- Shutdown
- Hibernation

I have tried a lot of kernels. I used Linux Mint: Kernel 5.4 works fine. Manjaro Kernel 5.4 works fine too. But, Kernel +5.4, the problem happens.

Additional info:
* Linux Kernel: 6.1.8-arch1-1
* KDE-Plasma, SDDM
* Dual Boot - Windows 10

Steps to reproduce:
- reboot
This task depends upon

It is not bypass.

I saw now that kernel +5.4 versions reboots the laptop without show nothing in display. No POST or grub screen. The system starts normally. Only reboot show black display. Only display after system load systemd-udev.

So it's not as bad as first thought. Either way, this appears to be an upstream issue relating to your specific hardware (probably Nvidia and/or firmware). Unfortunately not much Arch can do here. You could try the proper support channels (forum/IRC/etc) to see if anyone can assist in debugging the issue. General kernel troubleshooting advice here [1]. Please let us know if you make any progress. PS - you have at least 1 coredump in the logs which may or may not be related.
