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)

submitted 2 weeks ago by [email protected] to c/[email protected]

53 comments fedilink hide all child comments

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

Is it actual server hardware? I've seen some very weird things with real servers that take ages to reboot (I was assuming it was self checking or something). Are you sure its hung, and not just very slow to shutdown/reboot?

Is there any serial/monitor output before the hang?

Monitor output after shutting down:

I've given it 6 hours or so to shut down, so it's almost 100% a hang not a slow shutdown

seems its a nvidia issue, i also have that issue, the gpu locks and i need to reboot while the VM with the nvidia passthrough freezes. i need a full reboot from baremetal machine to stop gpu using all his power stuck, don't let it be for hours being on or you will kill your hardware

I have removed my gpu and the issue is still present.

yes sorry I read you after writting it, if you remove the GPU the log message is the same but without the GPU lockup line?

hi, a bios version revert solved the issue. thank you for the help!

[–] [email protected] 2 points 1 week ago

Perfect! Thanks for the feedback, good to know BIOS could solve hardware issues also. Weird to see you needed to reverd to fix the problems.
