Not working suspend and hibernation, /dev/snapshot ENODEV

[z0rel]

I'm trying to get suspend working on my box.

And the machine can not make the snapshot of the current state.

The main problem I think in the following
cat < /dev/snapshot

-bash: /dev/snapshot: No such device

My kernel version is 4.14.114. I tried to adjust the suspend and hibernation on kernels 4.19.37 and 5.1.1 but I got the same problem.

The state of my system:
Ram: 64GB, Swap 122,8 GB on SSD /dev/sdf3

s2disk

s2disk: Could not open the snapshot device. Reason: No such device

s2ram

KMS graphics driver is in use, skipping quirks.
s2ram_do: No such device

dmesg

[35176.521108] CPU0 is offline.
[35325.336627] PM: suspend entry (deep)
[35325.336630] PM: Syncing filesystems ... done.

cat /sys/power/state

freeze mem disk

echo mem > /sys/power/state
echo disk > /sys/power/state
echo freeze > /sys/power/state

-bash: echo: write error: No such device

strace s2disk

...
