I've also been experiencing a similar issue for some time - occurring
intermittently, not when I'm using only a small amount of RAM - where s2disk
would hang on writing the image:
s2disk: Saving image data pages (press backspace to abort) ... 0%
On Ubuntu 18.04 (currently 4.18 kernel)
This seems to be an old bug with uswsusp, which is an old package:
https://bugzilla.kernel.org/show_bug.cgi?id=75101
I think I first started using it because it was easier to set up and I
heard it was better for nvidia proprietary modules.
** Also affects: uswsusp (Ubuntu)
Importance:
Okay I found a way to get it working, first I gave up of uswsusp and
runned:
apt remove --purge hibernate uswsusp.
I basically followed this: https://askubuntu.com/a/1064114
but changed to:
resume=/dev/disk/by-uuid/70d967e6-ad52-4c21-baf0-01a813ccc6ac (just
the uuid wouldn't work so the path

Hang at freeze or thaw stage. Can't really tell.
Nothing much as I do as it's proprietary.

Both kernel 4.15 and 4.18.
I did increase the size of swapfile to match the RAM size

After researching a bit and with the help of a friend, I thought it could be
the i915 module due to the drm and rc6, which in fact was in use:

So... After reconfiguring uswsusp I increased logging level to 7. Also i
tried disabling the nvidia modules again but the same issue persists.
This is the information I could get:

The upper image shows what happens while trying to hibernate with nvidia
modules
No, I am 100% sure it worked with kernel 4.15.0-42 and with the nvidia
proprietary driver nvidia-415 before the version .27
Also always worked fine without any nvidia driver, specially for the
upstream kernel. I test this since more than one year...

With the recomended nvidia driver and low ram usage, the system
sucessfully hibernates, but then fails to resume and I get the login
screen instead. With high ram usage it hangs trying to save the image to
disk. That's a new behaviour to me.

Maybe try older kernel releases from Artful (4.13) or Zesty (4.10).

I don't think that's the issue. The nvidia problem I was used to is
being unable to resume. I also tested with the nvidia drivers disabled
and this issue still persists. Something I noticed is that I was not on
the recommended version of nvidia drivers which is 415 and I just
changed that now
So maybe it's caused by Nvidia driver update?

Ok so after running the right command to install the older kernel:
apt-get install linux-image-4.15.0-44-generic linux-headers-4.15.0-44
linux-headers-4.15.0-44-generic linux-modules-extra-4.15.0-44

before with 4.15.0-43. So We
Alright, today finally had some time and installed older kernels.
4.15.0-42 , 4.15.0-44, 4.15.0-45 and on the last I had the same bug as
always. I installed the older linux images, with apt, and runed
initramfs:
# update-initramfs -k all -u
update-initramfs: Generating
Linux kernel and DKMS.

As I said, the major change that I remember was updating from ubuntu
18.04.1 to 18.04.2. I'm attaching my apt history log to this message. I
am 100% sure that hibernation wasn't crashing and worked flawlessly on
02/06/2019 and it wasn't anymore in 03/04/2019.
The bug I'm trying to describe
Sorry this is a bit confusing. The bug description says it works with v4.15 but
now it doesn't?
What changes made the hibernation stops working?

A weird non tech way to describe it, which is what I can tell, Is that it seems
like when my system haven't used more than 2gb of memory yet, I am able to

Yes this is exactly how this this is happening. kernel 4.15 + propretary
nvidia drivers, either with those drivers enabled or uninstalled. Also
tested on kernel 5 without nvidia drivers.

to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v5.0 kernel [0].
If this bug is fixed in the mainline kernel, please add the following

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
unsure if that's the kernel or not, but that's a better bet that the
