One-Line Linux Patch Fixes AMD s2idle Failures For Some Ryzen Laptops

Guys, I am shoping for a 14", and I saw the Lenovo L14 AMD Gen2, and I am still shocked..

The amount of bugs that are out there with rizen3 laptops..
I think, maybe I will wait more 1 year, and see if they got something working..

on 5.15 kernel I still loose 10% battery overnight on my T14, I've seen people saying mashing the keyboard doesn't wake the laptop too, im guessing this will fix that issue

I also backported it to my old 5.14 "backup" kernel and it gets suspend and resume working there - good work

I had a similar issue on my Asus G513QY, it was fixed in 5.15-rc1, without this change

I've just tested it locally - fortunately no regressions

Sounds like my Lenovo 16ach with the sams processor suffers as well from this bug. I wondered already why it can't wake up from suspend, but I had no time to investigate.

Now they should increase that number to some big value and debug what is the real issue.

Read the bug report, they actually tried that first, and it didn't help.

That's surprising. Reminds me of the Atari 2600 era in where you had to time every read/write precisely to get a correct picture since its graphics chip lacked a framebuffer and was nothing more than a line generator.
