hello all...

i tried it already in the german forum, but unfortunatly without success. maybe here is someone, who have some advice for my problem:

i've bought 2 used Lenovo PC (M725s -> AMD CPUs) to test proxmox for my new homelab. i've installed proxmox succsessfully, make all available updates and used it for a while (nothing fancy)

but with the first restart i have to determine, that the system won't really restart. it will stuck before the bios screen and the power fan is running on high speed. you can press ctrl-alt-del, but nothing happens. the only "solution" is to unplug and replug power. after that the system will start normaly. even pressing the power button for a few seconds to shutdown won't change the situation.

additionally to that, i have the same issue with shutdown. after a shutdown (it doesn't matter if it's the shutdown command via shell or the shutdown via gui) i have the same issue after pressing the power button to start or wake up with wol: the system will always stuck before bios.

and i have this problem on both computers.

what i tried so far:
- updated the bios and reset to factory settings
- disabled fastboot and secureboot
- reinstalled 2 times

with Windows OS, i have no problems.

any ideas how to fix this problem ?

You can instruct the Linux kernel to reboot using a specific method using the reboot= kernel parameter (search for reboot= but you'll have to find which reboot method to use experimentally). The Proxmox manual has a section on editing kernel parameters. I've used it in the past when a system would freeze instead of properly rebooting,
However, I did not have the exact same issues what a power disconnect was necessary nor did I have the same issue after a shut down. Maybe it's a Lenovo /MiniPC specific issue (as those system often have quirks that "normal" server systems don't have)?

When you say "bios screen", what do you mean exactly? I'm not quite sure I understand.
 
I only skimmed your post - but some things that come to mind - that I'd probably check.

Is the PC set to auto start on power status? (Sometimes known as always - ON, restart on power restore etc.). In other words, when you re-plug the power supply back in - does it go straight on - without pressing the power button? If it does - try setting it to off in the BIOS - for testing.

Do your USB sockets (or any of them) have power when the PC is off but plugged in?
I don't know what your BIOS looks like - but does it have an option to power USB even when off. If it does - change it.

Have you noticed - BIOS settings not always being saved/retained. Check the CMOS batteries on those used PC's?

Check the physical power button? (Multimeter continuity check, that it is constantly connected/disconnected while pressed/unpressed).

If you hold it down for a long time does the machine always power off?

with Windows OS, i have no problems.
Different drive/medium? Without secure boot? Did you wipe the keys enrolled in the BIOS?

What happens if you install plain Debian?


If my mind gives me other ideas I'll update if I remember.


Edit: I found this post that looks fairly similar on the same machine.
 
I have heard of something similar because of a run state with some cpu's not changing as they should, during a reboot. I can not find it right now, but does the bios have a setting for TDP or power levels? If it does set it to max and try it.
 
i hope this might help someone

i'm very new to linux, but i had the same problem with my m725s sff where the computer wouldn't restart and hang on the lenovo bios screen. booting fine if i cut down power for 10 seconds. I uptated bios via ISO and enabled secureboot after clearing keys and now it reboots fine. i was having this problem with proxmox and mint both.
