Created attachment 287451 [details] Kernel Config When using 5.5 branch kernel my computer wouldn't go into the sleep state any longer. Trying to sleep would almost work but the computer never really "turned off", keeping fans running. Trying to resume from that state was also absolutely impossible, as it seems the computer didn't get to sleep, hence it was not possible to wake it. Bisecting identified 8aaa112a57c1d725c92dfad32c0694bd21b374d0 as the offending commit, which makes sense as this is "net: atlantic: refactoring pm logic". This was done directly on vanilla kernel tree. Not sure how to exactly debug where the issue is in the code, but I can run other tests as needed.

Hi Carlos, This is expected to be fixed in current "net" tree. Is it possible for you to test this tree? The fixing commit is 52a22f4d6ff95e8bdca557765c04893eb5dd83fd. Or you may wait until 5.6-rc3 - it should contain the related fixes. Thanks!
Igor, I have just applied 52a22f4d6ff95e8bdca557765c04893eb5dd83fd against the 5.5.4 kernel and sleep is working again. Not sure if we will want to just have it on 5.6 or fix on 5.5 tree too. Also, because I don't know how the issue tracker work here in the kernel, I will leave it to your to change the ticket Status. Thanks for the fast reply!
