Laptop fails to resume from hibernation (suspend to disk) after update to 18.04

For the beginning i say, that hibernation worked perfect on 17.10 on my hardware, and it doesn't look to me as a hardware problem now. Now when i'm putting my laptop to hibernation either by systemctl hibernate or hibernate it does write memory content somewhere on the disk, but while i'm starting it again, it looks like the kernel or initrd can't find the proper hibernation image. What i tried:
Put RESUME=UUID=cac3c850-bc33-44ab-adb4-41dcb5403e6f into my /etc/initramfs-tools/conf.d/resume, and do update-initramfs -u, this actually made things worse, because it just made the boot slower and i had to wait until it will say "giving up on resume" or something like that. The UUID is correct, i checked with blkid, and i use this as a swap partition, checked with swapon --show.
I tried to remove it from /etc/initramfs-tools/conf.d/resume and add resume=UUID=cac3c850-bc33-44ab-adb4-41dcb5403e6f to /etc/default/grub, and do update-grub, and also checked that it has been passed to kernel by cat /proc/cmdline, but also no luck. So how can I make ubuntu 18.04 resume after suspend? Or at least how can i debug issue more, to find out what's the problem exactly?

It's probably a kernel bug. Have you tried booting with previous kernels? Hold shift after the startup and select a previous kernel to start with. If hibernation worked on that remove the new kernel and kernel header.

Well, i will try, but what setup should i use? the/etc/initramfs-tools/conf.d/resume, or kerel cmdline? U use 4.17.0-rc4 kernel.

@SadeghGhasemi, trying other kernels didn't help, i think the bug is somewhere in initramfs-tools, maybe it looks for hibernate image somewhere else, but i have no idea how to debug it.

Did you try addingresume=/dev/your/swap/path/heretoGRUB_CMDLINE_LINUX_DEFAULTin/etc/default/grub? (don’t forget to runupdate-grubafter) I had the same problem as you, and that’s all I needed to do to get hibernate working in 18.04 (other than making my swap partition large enough).

yes, i tried. Also, what hibernation software should i use?systemctl hibernate?hibernate?pm-hibernate? Which one? Or they all doing the same?What do you mean by large enough? I have 16gb of memory, but 8gb of swap, but it wasn't the issue for resuming before, all it may do - not to suspend, if swap isn't enough, bot now it goes to suspend and never resumes.
