    Great news! Laptop suspend has been broken for so long on Linux(at least on my previous Lenovo Ryzen laptops), so I'm exited
    Now if AMD could fix power consumption for video playback(https://gitlab.freedesktop.org/drm/amd/-/issues/3195) then the Framework 13 AMD is looking like a great Linux laptop to get!

        Nice, I've had a few issues on my desktop as well, and suspend never worked off my USB nvme drive on that system.

          Sleep/low power mode makes my Vivobook with Ryzen "5000" Zen 2 not work right at all. Failure to shutdown, wifi won't resume, tons of issues even today. Hopefully this helps some of it.

            Genuinely curious what is wrong with S3 sleep, why is S2idle the big new thing? S2Idle always seemed like such a Windows world thing to me.

              This change will only help a very specific problem with BIOS. If you run https://gitlab.freedesktop.org/drm/a.../amd_s2idle.py and it flags NVME as a problem it will help that NVME issue.

              If you guys have other issues; please start with that script and open up bug reports if you have problems even with doing the things it suggested.

                Is there some kind of BIOS conformance test suite that should allow manufacturers to check compatibility before shipping borked laptops?

                Also, there is far too much garbage happening outside the OS these days. UEFI is an operating system of its own now...

                  Speaking of NVMe and Ryzen laptop issues .. I think kernel 6.9.4 (and I assume 6.6.33) might have finally fixed an issue where my laptop's NVMe disk would disappear when on battery (Metabox NL50NU or RU, not sure. A Clevo model anyway, Zen 2 Ryzen 5700U), causing the system to become unusable. Anything in memory would continue to function, but disk access was impossible (I/O errors). This would happen anywhere from a minute or two to 15 minutes after boot and being on battery power. The other day I used the laptop on 6.9.4 for about 5 hours on battery, going in and out of s2idle, and no issues.

                    The NSA requires the ability to wake any device in the world in an instant, with S3 on some devices this did not work sometimes. Thus, s2idle was needed to ensure the network connectivity remained intact to the ME and PSP chips.
