Linux server hangs on shutdown
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

edit: already on the latest bios version.

in reply to potentiallynotfelix • • •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?

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

I'd try uninstalling nouveau completely and see if the issue persists for you

in reply to potentiallynotfelix • • •I don't have an Nvidia GPU so I don't have any experience with it but a quick search brought me to Nvidias website and the instructions seem to line up with users answers on other forums.
Disable it here docs.nvidia.com/ai-enterprise/… or apparently installing Nvidias proprietary drivers automatically blacklists Nouveau.
