Just to be sure: could you check the behavior with the kernel in OBS Kernel:SLE15-SP5 repo?

If the problem persists, please check with the kernel in OBS Kernel:stable:Backport.  This is a 6.4.x kernel built for Leap.

I am experiencing similar problems and I can test the backport kernel. But before I start, is the backport kernel signed or do I have to disable secure boot?

It's an unofficial build, so disable Secure Boot, yes.
All kernels in OBS Kernel:* or home:* are unofficial builds in general.

(To be more precise: it's signed with a downstream key. You may deploy the cert manually if you want, too.  Each OBS project has its own key, so each project may need a different cert.)

Tried both repos' kernels,

5.14.21-150500.143.1.g4919d63.x86_64
6.4.1-lp154.2.gb8cc951.x86_64

That also stuck and frozen-black screen after 21 times sleep-awake cycles.

If the problem is seen on 6.4.x kernel, it's something to be addressed in the upstream at first.

Do you get any kernel stack traces or such useful info for debugging?

I am not very familiar with this, can you give me an example of how I should do it?

Check the kernel log of the previous (crashing) boots, either via journalctl or /var/log/messages, depending on the setup.  Do you see any traces by a kernel crash / Oops?

Journactl log file after resume issue.

Through a quick glance, there is no sign of crash in the log, unfortunately.

And, the screen-freezing is not only about the graphics, but also the whole kernel doesn't work?  For example, no remote access possible?

Var/Log Messages.

When freezing/black screen occurs then nothing works even TTY options.

In the last log, we see lots of errors from nouveau.  Could you try to blacklist it and retest?

Var/Log Messages v2

Strange cause I'd not have nouveau driver when I use TW but it has not work with new kernels too.

Tried after blacklisting nouveau and cycled sleep-awake resume, after 21+ cycles it once again frozen.

added last operation updated log message.

now I completely removed nouveau and taboo it, gonna retest sleep resume against that frustrating issue.

Did you enable nouveau via force_probe module option for Leap 15.5 kernel?
Leap 15.5 kernel has a downstream patch to disable nouveau for the recent chips, and I thought it should prevent it loaded.

In anyway, I see a few graphics related messages such as
  Fence fallback timer expired on ring gfx_low
which might be relevant.  But who knows...

There is another test kernel with the missing amdgpu fixes, and it's ready in OBS home:tiwai:bsc1212961 repo.  Could you give it a try?

I did not enable the module. After removal of nouveau still no chance for resume.

wanna try your test kernel but cannot install due to;

"No update candidate for 'kernel-default-5.14.21-150500.53.2.x86_64'. The highest available version is already installed."

rollback to leap kernel to switch from 6.4.x to 5.14 but still get this error.

For testing kernel packages, the easiest way would be to download kernel-default.rpm (and kernel-default-extra.rpm and kernel-default-optional.rpm for Leap), and install them with "zypper install".  You can pass --oldpackage option for installing the old kernels.

Also, I recommend to increase the number of installable kernels beforehand.
Edit /etc/zypp/zypp.conf, and add more entries to the line defining "multiversion.kernels", e.g.
  multiversion.kernels = latest,latest-1,latest-2,latest-3,running

Your test kernel worked without any suspend-sleep resume issue. I think you have fixed something on it. Tried several times more than 30+ sleep-awake cycles and no freezing, black screen but only sometimes in first seconds black screen to normal display. However this is not huge problem maybe related to my plasma theming.

Please let me know when I can use this fixing with official repo release? Also would like to try with TW's latest test kernel on yours fixing.

Thanks mate.

Good to hear!  I sent a PR to SLE15-SP5 git branch for inclusion, and hopefully it'll be included in the next maintenance update in July.

You can keep using my test kernel until the fix reaches to the official repo, of course.

Should I change bug's status to resolved > fixed or upstream?

Let me do that :)

BTW, it's not sure whether a maintenance update will happen in July.
Check the changelog and see whether the fixes referring this bug entry (bsc#1212961) appear.

I had no time try the new kernel, as I suspend and resume not that often.
Thanks to you both.
