Are they linux VMs? If so, there is a bios update coming out to resolve an RdRAND issue. It also fixes Destiny 2 issues. Be on the lookout for 22.214.171.124ABA bios update for your board if you are running linux. Especially versions of Ubuntu.
You could reach out to them. This is a major patch. AMD just released it to their partners yesterday. Give it time and it should be good. For now you may want to go back to your 1700x.
Also, this issue doesn't affect EVERY linux distros, but a lot of them. Especially newer ones like Ubuntu 19.04. There is a collision that happens between systemd and the RdRAND instruction set causing the process to stall and OS not to boot.
