AMD Has An Important Suspend/Resume Fix With Linux 5.15

I was the 'user' who reported this issue. Glad to see that the fix made it into 5.15.

Would you happen to have a link to the ticket? I can't find it.

No fan spin-up even under load, and control buttons (brightness, volume, ...) not working are pretty critical issues. Especially the former is just dangerous for the hardware... Any chance this is getting backported to 5.14? Anyone know if there's any way/place I can petition for this? I have one of the affected laptops.

Depending on the laptop, it may have a "secret" key combination to force the fan to maximum if really worried. On my last laptop it was Fn+1.

The control buttons not working seems to depend on the ACPI implementation? My LG Gram had half the control buttons not work (I think only Flight Mode worked on the clean install) until I installed LGs software to control it - even in Windows - which is really annoying as the LG software is terrible. Keeps trying to update my chipset drivers (even though I'm actually running newer ones I installed manually from Intel) but every time it installs them it BSODs the laptop.

I'll put my LG Gram to sleep tonight, rather than shutting it down and see how much if any drain there is, because now I'm curious.

Just to follow this up. I tried it asleep overnight and it lost about 5%.

That's interesting. S2idle works flawlessly with the 5.13 kernel on my Lenovo Yoga slim 7 with a Ryzen 5800U. Unfortunately something broke suspend in 5.14 so I had to go back to a 5.13 kernel again. What is the best way to report this regression? The distro or try to report directly upstream?

Hmm, I'm not sure where the best place to report is. My initial issue appeared to be due to a stacktrace in the amdgpu drm module, so I reported it there. It ended up being completely unrelated to the issue at hand, but it got the right people involved.

What sort of behavior are you experiencing? It worked in 5.13 for you, but 5.14 is broken. Do you have the ability to try any of the RC kernels, or bisect the regression? If I/we know more about what is no longer working, we might be able to point you in the right direction.

The 5.14 kernel is the first version that supported s0ix on the Renoir platform (e.g, my Ryzen 4700U-based HP Envy x360 13") out of the box. I've been watching the patches/activity around this significant interest for about a year now (since I got the laptop and reported the bug that ended up with this getting implemented/fixed).

My HP 15s-eg0355ng drains 15% even when shut down/halted. On top they closed my request for the UEFI bin file with a friendly "not supported". All UEFI upgrades are buried in exe files. That's the downside of a 300 € laptop.

why should i change the gpu ?
The gpu hang is annoying, but that's it.

I don't know how do you live with it. Those hangs drive me mad so badly, that eventually I lost my motivation to try running games at all. What's the point, if it can crash any minute, and instead of fun you get frustration? When I realized this problem, I ordered RX550, and had no problems ever since. Yes, it's much slower, but my user experience with it still was much better than with Vega.

On my old X1 carbon 5th gen, I never noticed any drain overnight, it would have been less than 5%

I have a Carbon X1 gen 9, intel obviously. Modern suspend works really well, I never thought it possible. Lenovo has confidently labelled it the Windows/Linux option in the UEFI settings. S3 is there too ("Linux"). I hope these AMD fixes benefit the AMD IdeaPad my son has. We have it patched to run S3 and it works, but we have to use an older kernel.
