System failes to hibernate

Nothing happens when invoking

systemctl hibernate

however I can see that uart returns an error code when suspending. After invoking the command multiple times I can successfully hibernate.

journalctl -e:

May 17 14:12:11 pcarch systemd[1]: Stopped target Sleep.

`pm_runtime_force_suspend` returns -16 (EBUSY), device or resource busy. How can I pinpoint the problem and how can I solve this? My intention is to be able to hibernate.

Yes, that's how I got it working in the first place. I only have this issue on my laptop (which is relatively newly setup, it acted the same when I first set it up), and not on my stationary.

Re: System failes to hibernate

May 17 14:12:11 pcarch kernel: port dw-apb-uart.3:0.0: PM: failed to freeze: error -16

It looks like this dw-apb-uart doesn't want to sleep. What is connected on that port?

Tbh I don't really know what is connected on that port or how I can figure that out, after some more digging I found out that it might be something about the 8250_dw module, from an issue on Github.

your laptop to stop recognizing your battery so it isn't much of a fix but hope this helps somehow.

Can you suspend the system from the rescue.target  (2nd link below)?
