Computer randomly fails resuming from hibernation

I've got an Acer Aspire E5-571G, and I've noticed that hibernating for 50 times, 13 times fails. With no reason, i've tried almost everything from unplugging usb devices, waiting time etc. It seems to be completely random. I've followed step-by-step the guide in the wiki.
Basically, when I resume my PC from hibernation, sometimes it reboots automatically after systemd loads the resume hook (after like 8/9 seconds, more or less like if it resumes correctly)
I can't really understand why, there are my latest kernel logs (I've rebooted frequently to try hibernation)

I've updated Arch everytime. I'm using the acpi_osi= kernel command but i've also tried without it. Maybe I need to patch my DSDT? I've tried to create one but grub doesn't seem to load it.
Anyway, in my kernel logs I can see come PM-releated messages like maybe when it failed to resume.

"Dec 10 13:53:05 luky-notebook kernel: PM: Starting manual resume from disk
Dec 10 13:53:05 luky-notebook kernel: PM: Hibernation image partition 8:6 present
Dec 10 13:53:05 luky-notebook kernel: PM: Looking for hibernation image.
Dec 10 13:53:05 luky-notebook kernel: PM: Image not found (code -22)
Dec 10 13:53:05 luky-notebook kernel: PM: Hibernation image not present or could not be loaded."

Re: Computer randomly fails resuming from hibernation

is your /dev/sda drive always detected as /dev/sda or sometimes under a different name?

I don't think. But I'm using a swapfile as  swap space

Tried also with a swap partition instead of file. Nothing changed.
