bug#57583: Guix cannot resume after hibernation

[Yusuf Talha]

Hello.  I'm using Guix System on my Librebooted Thinkpad X200 laptop.  
Suspending to RAM works perfectly.  The problem is, when I run "loginctl 
hibernate" it writes to the swap partition and powers off successfully.  But 
when I try to boot up and resume from swap, it just ignores it and starts up 
like it wasn't hibernated before.  And also I have to run "sudo swapon 
/dev/mapper/matrix-swapvol" to re-enable my swap partition.  swapon says:
"swapon: /dev/mapper/matrix-swapvol: software suspend data detected. Rewriting 
the swap signature."

I have added "resume=/dev/mapper/matrix-swapvol" to the kernel-arguments list 
in config.scm.
In addition to that, I see these messages on the dmesg log (I have no idea what 
they mean):

I haven't encountered this problem on any other distros.  You probably realized 
that I encrypted my disk.  Hibernation wasn't working while I was using Guix 
without encryption a few months ago either.  So I don't think LUKS is the 
problem here.

I would be glad if you can help me with that.  Thanks in advance.
