Waking up from suspend sometimes does not work on kevin device

@WizzardSK can you add test cases here?

[WizzardSK]

I am not sure what you mean. I try suspend, mostly it works, sometimes it does not.

[apple-corps]

The idea is that you describe a way to reproduce your bug.

So you can trigger a suspend like:

sudo systemctl suspend

Then the expectation is that you do some next steps [describe them] and it resumes. That way the bug fixer has a test case. If you can elegantly describe a test case, it will make it easier to fix the bug.

[WizzardSK]

I run the command: sudo systemctl suspend OR I close the lid.
Mostly I am able to resume the OS, after opening the lid or pressing some key. maybe 5 or 10 times it works and OS resumes, but sometimes not.

Fair enough! I'll let the cadmium devs take this up, until I get involved

That's not a mature and acceptable answer, please go back to work.

@WizzardSK I think maybe you can capture logs which contain the suspend cycle, for a functioning and non-functioning run. I do not know where to look at the top of my head. Can you look into this?

This is how it looks when not working:
