system not reliably waking up from systemctl suspend

hey guys,
i'm having this issue with systemctl suspend for some time now. it mostly works, the system is suspended and it also properly wakes up most of the time. but every now and then, the screen and input devices aren't activated when waking up, leaving me no other choice than forcefully shutting down and rebooting my system, which ofc is really annoying.

i already did some research but didn't really find anything meaningful. most of the problems seem to be acpi issues with laptops, but my system is a desktop computer.
i also looked for errors in the syslog with journalctl, but there isn't anything that seems to be related to my problem.
i also tried switching to the lts kernel, to no avail.

e.g. in my last session, the problem occurred again, but this is all the suspend related information i can see in the log:

Dez 10 16:54:42 cthulhu systemd[1]: Reached target Sleep.
Dez 10 16:54:42 cthulhu systemd[1]: Starting System Suspend...
Dez 10 16:54:42 cthulhu systemd[1]: session-1.scope: Unit now frozen-by-parent.

Dez 10 16:54:42 cthulhu systemd[1]: user-1000.slice: Unit now frozen-by-parent.
Dez 10 16:54:42 cthulhu systemd[1]: user.slice: Unit now frozen.
Dez 10 16:54:42 cthulhu systemd-sleep[41987]: Successfully froze unit 'user.slice'.
Dez 10 16:54:42 cthulhu systemd-sleep[41987]: Performing sleep operation 'suspend'...
Dez 10 16:54:42 cthulhu kernel: PM: suspend entry (deep)

here's how suspend is configured atm:

cat /sys/power/mem_sleep
s2idle [deep]

/etc/systemd/sleep.conf contains the default settings which are all commented out.

system info:

mainboard: MSI PRO B650-S WIFI (MS-7E26)
cpu: AMD Ryzen 5 7500F
gpu: AMD Radeon RX 6600 XT
ram: G.Skill F5-6000J3238F16G (32G)
ssd: Kingston KC3000/FURY Renegade NVMe SSD

graphics driver: amdgpu
display manager: wayland
window manager: sway
kernel version: Linux 6.17.9-arch1-1

any pointers as to where i should start debugging this are appreciated.
please let me know if any other information is needed.

I have 3 machines, that for a while now, they wake from suspend and then immediately suspend again.

This solved it.

lxterminal -T Suspending --geometry=40x6 -e "sleep 1; sudo systemctl suspend; sleep 2"

That gives more time for <something> to happen. Just a thought for you.

@cthulhu1010 Don't do that
This isn't properly debuggable since the system doesn't wake up to give you any indication as to what's wrong.
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

- we'll have a look whether anything generally suspicious shows up.
Ideally post a journal including a successful S3 cycle
Can you btw. reproduce this w/ s2idle?

@teckk, sounds different from the OP - https://bbs.archlinux.org/viewtopic.php?id=311215 => https://bbs.archlinux.org/viewtopic.php?id=308457 ?
