> 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 addition to that, I see these messages on the dmesg log (I have no idea what
