Can't resume from hibernate (suspend to disk) about skulls

[merge]

I cannot reproduce this and I'm resuming fine from hibernation. I guess you have a different issue. What version of Linux are you running?

[varac]

I'm using Ubuntu 18.04, kernel 4.18.0-13-generic.
It worked fine for be before flashing coreboot.

I use skulls 0.1.0 and its released non-free images. Everything works so but but not resuming from hibernate. These are the regarding boot msgs trying to resume:

It works for me if I run systemctl hibernate with root privileges, without root privileges I get the same boot messages and the resume fails.

Environment:

• Ubuntu 18.10
• 4.18.0-13-generic kernel
• systemd v239

Same for me. I guess my initial issue was failing resume from hibernate, when I hibernated without sudo.
I'm now using the hibernate option from the gnome menu and everything is fine.

For me this issue can get closed. @apraile ?
