Description Michal Suchanek 2023-06-19 09:59:09 UTC 
This is a problem with

kernel-default-6.3.4-lp154.5.1.gbfc9f93.x86_64
kernel-default-6.3.8-lp154.2.1.g627a49e.x86_64

and is a regression since

kernel-default-5.14.21-150500.53.2.x86_64

The problem is not reproducible reliably - sometimes tying suspend right after boot waking the system works but most of the time it stays asleep and cannot be waked.

Could you try 6.2.x kernel from OBS home:tiwai:kernel:6.2 and check whether the problem already exists?  We need to narrow down the regression range.

That's built for TW, not Leap

The package for Leap is found in "backport" repo of the given OBS project.
Comment 6 Michal Suchanek 2023-07-02 11:11:13 UTC 
Seems to work with kernel-default-6.2.12-lp154.1.1.geb3255d.x86_64
Comment 7 Michal Suchanek 2023-07-08 12:52:32 UTC 
kernel-default-6.2.12-lp154.1.1.geb3255d.x86_64 survived quite a few suspend cycles so that's quite positively working

kernel-default-6.4.1-lp154.7.1.g3561b10.x86_64 survived a couple of suspend cycles, looks promising.
Comment 8 Michal Suchanek 2023-07-10 07:30:17 UTC 
Looks like only Linux 6.3 was affected - not before, not after.
