Title:
s2disk freezes at saving image to disk (hibernation)
Status in linux package in Ubuntu:
Incomplete
Bug description:
This started happening after I upgrade to ubuntu 18.04.2. In 18.04.1
hibernation was working flawlessly on my machine. (with kernel
4.15-46! not a kernel issue then?)
Another thing that got updated recently was nvidia drivers which were
known to cause hibernation issues, but those were on restoring the
snapshot.
http://imgur.com/gallery/jOyHEcL --> I get stuck on this screen after
running hibernate or pm-hibernate. (sys-req REISUB combination works
there and is the only good way to restart I found)

grep hibernation
I could find nothing scrolling up on syslog about the hibernation process or
with grep....
An interesting Note is that if I run hibernate just after I boot, it works
and resumes perfectly! But after some system usage it randomly has that problem
if I try. The percentage it freezes at is also random, sometimes 0, 1 even 30
once.
