[SOLVED] System does not resume after suspend or fails to suspend

Hi, slight problem. When the system is suspended it reboots when resumed or it shuts off when trying to suspend, not really sure which.

Anyway, heres some relevant journalctl entries.

mar 14 21:29:04 luluco systemd[1]: Reached target Sleep.
mar 14 21:29:04 luluco systemd[1]: Starting Suspend...
mar 14 21:29:04 luluco systemd-sleep[6492]: Suspending system...
mar 14 21:29:04 luluco kernel: PM: suspend entry (deep)
-- Reboot --
mar 14 21:29:32 luluco kernel: Linux version 4.15.8-1-ARCH (builduser@heftig-25495) (gcc version 7.3.0 (GCC)) #1 SMP PREEMPT Sat Mar 10 00:00:33 UTC 2018
mar 14 21:29:32 luluco kernel: Command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=a9b305d9-6022-413a-9f49-cd1f1bd13dc6 rw resume=/dev/nvme0n1p2 quiet

Is this how it's supposed to look? Is it skipping steps when suspending? From this it looks like it's shutting down while trying to suspend as it lacks any calls for resume or similar, but I'm not sure.

Maybe worth mentioning, I think this behaviour started after I upgraded to the latest kernel (4.15.8-1) from (4.15.7-1). I tried to see if downgradingt 7-1 would work since it had been working on that version for atleast a week, but alas, that was not the answer.

Anyway, I'm kinda stuck right now. Would be cool if someone could shed some light on how best to tackle this ^^'

Re: [SOLVED] System does not resume after suspend or fails to suspend

Someone might have better thoughts. But from personal experience, and seeing others have this type of issue in the past, the suspects are usually one of (in no particular order):

(A) firmware/BIOS-related. For example, did you update your BIOS recently, or mess with its settings? And how new is this hardware, and your arch install on it?
(B) Intel TPM related. Do you have it? If so, did you do something like trying to disable it? This can be a cause.
(C) Kernel parameters related -- this is sometimes related to the above. Have you tweaked these at all recently? For example, ACPI-related ones.
(D) Graphics card related. What is your graphics hardware / software setup? And do you still have this issue when suspending when just logged into the Linux VT (no X11/Wayland/etc.)?
(E) Kernel upstream regression. Have you tried booting into linux-lts? And could you try again your attempts to downgrade the kernel to an older version (double checking you updated bootloader, etc.). If you can find this to be the source, then bisecting the kernel would be my choice: https://wiki.archlinux.org/index.php/Bisecting_bugs

In general, there are many complaints of this kind, you're not alone. Try to search some recent mentions of this online, particularly ones related to your hardware.

Re: [SOLVED] System does not resume after suspend or fails to suspend

Suspend is working again after updating to 9-1, so it probably had something to do with the 8-1 kernel and me doing something wrong when downgrading from 8-1 to 7-1.

Thanks for the input, GenkiSky! I'll be sure refer to your list if the problem crops up again in the future(and it isn't the kernel again).
