Linux server hangs on shutdown (lemmy.fish)

I've had two server oses here: alma linux and debian(currently). On both of them, they will hang when I shut them down from cockpit, and they hang at the end of the shutdown.

Also, it takes an hour to a day to have this issue start. if it's restarted two times in a row quickly, it works perfectly fine for some reason.

What I've tried:

setting "acpi=off" and "acpi=force" kernel parameters in grub
removing my nvidia gpu(i was using nouveau drivers)
changing distros

nothing worked. here are some things that both distros had in common with eachother:

systemd
cockpit
libvirt & qemu
docker

does anyone have advice? nothing i've seen online has worked. thank you for suggestions

reboot: machine restart

This makes me think it's a motherboard issue.

The system is done with its shutdown process and issued the reboot command, but the motherboard didn't restart.

There could be some electronics components which get wedged over time. My sound card will occasionally not boot unless it has been completely powered off for 30 seconds or so.

a bios update revert fixed this. you were correct that it was mobo related.

That's great, it beats having to buy new hardware!

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
