suspend/hibernate doesn't succeed on old AMD64 hp625-laptop

on my uptodate-Archlinux-Environment with Linux arch 4.14.71-1-lts #1 SMP Thu Sep 20 20:14:07 CEST 2018 x86_64 GNU/Linux or any other Kernel (3.18,  4.4, 4.14.72-VanillaKernel ), systemctl suspend/hibernate didn't succeed, so I broke it down to a lower level with echo mem/disk > /sys/power/state where the same happend, the echo didn't return.
In dmesg I could see at last:
[14459.258227] PM: suspend entry (deep)
[14459.258232] PM: Syncing filesystems ... done.

when I then interrupted the echo-command with Ctrl-C, the suspend continued and finished properly with

[14633.961190] Freezing user space processes ... (elapsed 0.002 seconds) done.
[14633.963531] OOM killer disabled.
[14633.963533] Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
and so on

The system is full responsive while the suspend is pending, so it looks like its a problem with freezing userspace-tasks, but I don't see any message
With an Ubuntu-Environment and the same 4.14.72-VanillaKernel but 32-Bit and not 64Bit like in the Arch-Environment but same .config, everything works fine, so I suppose its an arch-issue.

This looks very strange to me, because in the 20 years before, I'm working with linux, I had problems with the resume like many others here, but never with the suspend

Current LTS is 4.14.90 so assuming that the rest is up to date, are your kernel versions not matching ? Output of

pacman -Q linux-lts
uname -a

(also please use [ code ] tags for pasting command outputs) either way, do a proper complete system update, reboot and try reproducing with an actual up to date system.

If you still encounter an issue, post a complete dmesg, maybe if you are forced to reboot a journalctl -b-1 to see if any error was written while suspension failed, and a complete /var/log/pacman.log
