[arch-general] Hibernation not working

[Carlchristian Eckert]

Two days ago, I started looking into this again. After some adjustments, 
hibernation works for now. Dropping the solution here in case it helps. 
The likely culprit seems to be a RAM upgrade from 16 to 32 GiB. During 
this process, I forgot to adjust my SWAP partition, which was also just 
16GB in size.

I use ZFS, which fills a large portion of the RAM with L2ARC data, so 
that might have been just too big for the swap partition.

TL;DR the size of the swap partition was too small.
