As Maciej Dziardziel suggest, I've rebuild 4.10.1 kernel and deactivated GPIO_AMDPT, GPIO_AMD8111 and PINCTRL_AMD. The system was booting correctly, however I cannot use any USB keyboard. So I've rebuild the kernel, deactivating only PINCTRL_AMD and everything is working fine now.
Here is my setup : Aorus GA-X370-Gaming-5 with Ryzen 1800X.
