Hello, I am making this post after trying everything I could think of. I have 2 laptops (Thinkpad T480 and T580) that will occasionally hang when waking up from suspend. I have seen some of the forum posts about this issue, and have tried the fixes in these posts to no avail.
Symptom:
On my T580 after ~2 months of flawless operation (June to August), started to freeze occasionally when waking up from suspend. The "mute" key led would light up as expected (I have the laptop muted), but the power led is still in a slow breathing state, indicating the laptop thinks it's still sleeping. The cpu would get hot to the point that the fan will kick on, screen is off and the system will not go back to sleep after closing the lid again. The only way to recover is hard reset. The same thing happens on my T480 (same boot drive).
This is a sample of what the journal look like after the crash happened:

Sep 28 19:35:56 systemd-logind[1046]: The system will suspend now!This issue first happened on August 26, and it would only happen intermittently. I applied the fix from this: https://bbs.archlinux.org/viewtopic.php?id=296954, and it seemed to solve the issue for about 2 weeks before coming back earlier this week. I switched from my T580 to my T480 thinking it's a hardware issue with the T580, but the same issue happened. Using the linux-lts kernel also did not fix the issue.
I also doubt that systemd is the problem here, the logs show that I upgraded systemd from 255.7-1 to 256.1-1 on July 4, and this problem only started last month. To further test this, I have downgraded systemd, systemd-libs, and systemd-sysvcompat from 256 to 255 but the problem still occurs on both laptops. If anyone can give me tips on what's wrong or possibly how to get more detailed logs in the journal about the crash it would be greatly appreciated!
My setup:
i7-8550U (both laptops)
Both laptops have almost the latest BIOS, both have had extensive run time on this same boot drive without issue.
2x16GB Crucial ram (passed memtest)
Running sway (1:1.9-5) with swaylock (1.8.0-1)
linux 6.10.10
linux-firmware 20240909.552ed9b8-1
intel-ucode 20240910-1
systemd 256.6-1

Hi, I am using a Thinkpad x1 carbon gen 7 and I am experiencing the same issue. I tried using the linux-lts515 kernel and linux-firmware-20230117 but the problem was still there.
It also appeared about a month ago.
I tried disabling wifi and bluetooth before putting it to sleep but I am unsure if it was useful or not.
In its crashed state, the key lights might be on or off. I can't mute the speakers or microphone but the FnLock key works.
I remember doing at the time an UEFI firmware update to patch a vulnerability. I think it was this one. Did you also do an update recently or not ?

Nvidia driver problems seems to be happening with every other driver update

Well I'm not sure it's related since I don't have a graphics card on my system

Another Thinkpad not waking up from sleep anymore over here. Broke around the same time OP posted. Used to work just fine for a whole year. I changed nothing except applied the typical automatic updates via Pacman.
e. AMD CPU and GPU.

Same for me with my ThinkPad E14 Gen4 (no Nvidia inside, only AMD CPU and graphic card). Since some weeks (I don't know when), suspend hangs.
It seems to be a Mediatek regression in the 6.11.x kernel or maybe before. On my system, a valid workaround is to turn off bluetooth before suspend. If I do that, everything works as expected.
As you can see, it's not an Arch related bug, but probably upstream. Fedora users encounter it : https://discussion.fedoraproject.org/t/ … /134008/12
And I saw same regression mentionned on others forums (opensuse, debian).

Ok at least now we know a little more about the problem.
As I said previously I tried disabling bluetooth and I think I had less crashes. I wasn't sure if it did something but after your message and recent tests, I can see that it reduced the number of crashes (only one happened since).
