Suspend-then-hibernate not working since upgrade (december-2022)

@Nachordez, regarding the other issues you mention in your initial post, I have to admit that I have some trouble following and understanding everything :sweat_smile:

1

I was using flawlessly suspend-then-hibernate in my system. But since December upgrades it stopped working.

OK, that is what led me to the previous answer I posted (systemd v252 issue).

At change to linux515-5-15-84 I also suffered the infamous sound problem, so I was more worried about that question. But it seemed to start then. And then the solution was to change into linux60 or linux61 (both working fine for me, with the ibt=off booting parameter).

Which “infamous sound problem” are you referring to?

I am facing a sound problem for a week now (because I was not using my laptop with Linux for a while for professional reasons) but I was not yet able to identify precisely what the cause is or any workaround.

The sound works properly after boot and then, after some time or after resuming, no sound anymore. I am running the Linux kernel 5.15.85-1-MANJARO.

  • Do I have to upgrade to Linux kernel >= 6.x for the sound issue?
  • What does the ibt=off kernel parameter do in that regard?

But there were some problems with the suspend or hibernate options. Probably for the big tinkering during the sound problems. Reinstalling systemd package, to overwrite changes on modified files, solve that, and both are working nicely now again.

  • What kind of issue have you faced regarding suspend and hibernate?
  • Were they with the kernels 6.x?

I am asking because I face another issue with kernels > 5.15 where:

  • suspend works
  • hibernate works (state is written to disk)
  • suspend-then-hibernate works (the transition from suspend to hibernate)
  • BUT the laptop is not powered-off when hibernating …

Thanks in advance for your answers :pray:

PS: I hope I am not hijacking the initial topic (I am completely ok with simple answers that redirect me to other topics or RTFM links :smile: )
