i have ryzen 1700 summit ridge, just bought. run only linux and i get this:
[Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0)
using asrock fatal1ty b450 board. i set under advanced zen options power supply common current idle.
or something like that to overcome crashes while idle. which i did experience.
is this a defective chip that needs to be rma'd ???????
