I have an AMD Ryzen 5 2500U mobile system and use Linux kernel 4.15.4.
CPU microcode version is 0x8101004.
It´s not possible to suspend this system. Either it reboots or freezes. Usually it kinda freezes and can´t wakeup.
I´d like to know from the AMD gurus, is STR for Raven Ridge already implemented in Linux after all?
Or is there any good workaround, e.g. things like acpi_sleep=nonvs (though it does not help at all....)?
