Could a user with an ASUS Pro WS X570-Ace be so kind an try to boot (free) ESXi 6.7 (U3)?
I’m having PSOD issues when booting it (UEFI and CSM/Legacy), with the 6.7 U3 release image as well as with an installed version from a different computer that has the latest updated version on it.
The BIOS is the latest 1302 and as far as I know there should not be any catastrophic issues with ESXi and Ryzen 3000 except for the broken RDRAND with early AGESA versions.
