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.

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

@potentiallynotfelix As a diagnostic, I would suggest trying shutting them down by ssh in and then using systemctl to shut them down, if that works then you know the issue is with cockpit. If it hangs even when systemd is asked to halt then I would consider reverting to the previous bios and see if the problem persists.

Ok. Cockpit uses the shutdown command to shut down[src], but systemctl poweroff might work. I will also attempt to revert bioses if msi supports it. thank you very much!

@potentiallynotfelix Ok bet of luck. I've had all sorts of weird issues with systemd as of late, but not sure how many of those are inherent to systemd itself and how many are Ubuntu's config of same.

sudo systemctl reboot did the same. I'm starting to think this is bios related.

@potentiallynotfelix Well flash to an older and see how it goes. I've seen some wired bios issues. I've got an i7=6850k machine on an Asus motherboard, and after I flashed to the latest bios, the USB power strobed on and off every few seconds so keyboard and mouse would work then not work then work then not work. I thought something was broken with hardware but then found others had the same issue with the most current BIOS, flashed to one release earlier and all good.

Flashing an older bios seemed to succeed! I gave it 14 hours or so before attempting a reboot, and if seemed to reboot without stalling. I'll give it a few more days now and try another, but that seemed to have fixed it.
