Hey guys,
So I'am running arch linux on my laptop (Acer don't know the specific model). Since the kernel 5.6.6 (???) hibernation stopped working on my system, previously I had followed the arch wiki on how to make hibernation work, and it did work.

Ok so I decided to go and try to understand why it isn't working. Found on the docs of kernel a page about debugging suspension/hibernation, and that is what I am following, but I am stuck on one "step".

My system doesn't hibernate on devices test mode following that the docs says to do a binary search on the modules in order to find the module that can't hibernate. My question is how I'm supposing to do that ? (modprobe -r all modules ?)

Ps: Downgrading kernel to the last LTS makes the hibernation work. The only reason I am doing this is to try to get this bug or error to mainstream in order to fix it.

Been here a while so maybe I'll guess a bit.

I'd peek into the downlevel running acpi modules.

Appreciate your reply, unfortunately I am not an expert, I tried following this but I don't know what I am doing.

Suspend isn't working either, when running systemctl-suspend my laptop does suspend but the power led is still on (I will probably record it and add later), my journalctl gives me this

From my understanding it should be working ... But as I said previously the power led keeps turned on and I can't do anything with my machine unless holding power button to reboot.

Have you tried searching the archlinux forums?
It looks like you're not the only one.

Actually no I haven't going to give a look there and maybe open a thread there, and possible return with a fix

Thanks for the help !

Better check that your swap partition is still on I guess too.
