TONS and TONS of fixes have landed for s2idle since then. 5.15.y is the fi= rst kernel that you should be confident to use it. Please re-test with s2idle using 6.0-rc6. If that doesn't work let's fix i= t. > Is "echo s2idle > /sys/power/mem_sleep" equivalent to enabling s2idle via > ACPI? So I wouldn't need to reboot to change ACPI for testing s2idle. No, on AMD systems there are Pre-OS changes that occur when you use modern standby/s2idle. If you use s2idle when the firmware is configured for S3 y= ou will never get into the proper power state. > Actually S3 is very well hidden. I don't know a way to enable it directly= in > the BIOS. But it's in the ACPI tables. As you're patching the firmware this is not a regression. It takes more to properly enable S3 in Pre-OS code than changing a variable evaluated by the Linux kernel's ACPI interpreter.. Thorsten - this is not a regression, patching the BIOS like this is complet= ely off the beating path. We can't possibly support S3 in Linux if the OEM doe= sn't offer it in their BIOS. kolAflash - Let's focus on fixing s2idle for your system. With 6.0-rc6 and= an "unpatched" BIOS let's see if you have any remaining problems with it. --=20 You may reply to this email to add a comment.
