Summary

Hello, since updating to kernel 6.11.5 I am unable to wake my computer from suspend. This happens every time I try to suspend the computer, it doesn't seem to matter for how long it is suspended. After booting in the previous kernel (6.10) I can put the machine to sleep and wake up without issues.

Steps to reproduce

Suspend the computer from user interface
Try to wake up the computer

Expected result

The computer succesfully wakes up and can be used

Actual result

The computer stays frozen, doesn't output any image, doesn't react to inputs, doesn't show up on the network (can't ssh into it.)

Environment

Other comments

I have tried using HDMI cable instead of DP cable to conenct my monitor, no change. I have a NFS share and SAMBA share mounted on boot. I tried unmounting those before suspend, no change. Only succesful remedy was booting into the 6.10 kernel

The systemd log shows no information about the attempted wake up. Attaching log about the suspend journal.log

I have the same problem with a fresh install. Network Manager seems to be involved in this issue.

Curiously enough, after the last sync, my computer seems to be able to wake up again. I don't think I have changed anything relevant on my system, so it was probably something in the update.

Okay, I was too quick with my assessment, the bug is still present. But I finally found the culprit. TLDR: Mediatek mt7921e driver has some bugs.

I have a wireless card MT7921K (RZ608) from Mediatek and apparently it's a known troublemaker… I found this arch forum thread about the same issue. There are few issues for the driver of this wireless card on the kernel bugzilla, some of them seem relevant to my issue.

I added the kernel parameter (mt7921e.disable_aspm=Y) to my boot options - that on its own doesn't help.

What works for me is to disable bluetooth before suspend (I have wifi disabled all the time at this machine - maybe it's necessary to also turn that off). After that I can resume from suspend. If I have bluetooth enabled before suspend, it refuses to wake-up.

This part isn't exactly important for the bug, but it explains why I thought the bug was fixed: Apparently this wireless card also has a random issue, where it stops working. After I noticed that my bluetooth stopped working (and that must have happened the same moment my sleep started working) I stumbled upon this post from endevaour os forum that recommended to power off the machine and disconnect the power cord for a moment + press the power button. This restored my bluetooth functionality, but made the sleep issue reappear.
