That is unlikely since the whole series got merged through the pdx86/for-next branch, so either some other tree has the whole series or none of it. Also note that Randy wrote: "when CONFIG_SUSPEND is not set" The problem is that all of drivers/acpi/x86/s2idle.c is wrapped by #ifdef CONFIG_SUSPEND ... #endif Since AFAIK the whole amd-pmc driver's whole purpose is to allow s2idle to work properly. I think this can be fixed by simply doing: --- a/drivers/platform/x86/Kconfig +++ b/drivers/platform/x86/Kconfig @@ -198,7 +198,7 @@ config ACER_WMI config AMD_PMC tristate "AMD SoC PMC driver" - depends on ACPI && PCI && RTC_CLASS + depends on ACPI && SUSPEND && PCI && RTC_CLASS help The driver provides support for AMD Power Management Controller primarily responsible for S2Idle transactions that are driven from If you agree, please submit a patch with this change and I'll queue it up in my fixes branch.
