Description Ignacio Hernandez 2022-12-08 06:32:54 UTC

After updating the kernel to 6.0, the resume time has increased significantly, the only clue I can see from dmesg is:

PM: resume devices took 5.132 seconds


What information is needed to debug this issue?

I wonder if this is the same problem as described in bug 216706; if it look possible to you, please check if the patch from bug 216706 Comment 11 helps.

I rebuilt the kernel from my distro with just the patch recommended and it is much better, I am seeing ~700 ms resume times. 

I have the feeling that it used to be faster but need to go back to a 5.19 kernel and test that.

Thanks a lot for the help!
