Problem booting FreeBSD 12.2 on Hetzner Cloud CPX instance (AMD/KVM)

[PaulC]

I'm trying to install FreeBSD 12.2 on a Hetzner Cloud CPX instance
(AMD/KVM).

Unfortunately when I boot this from the 12.2 CD it doesn't find the
KVM virtio network/disk devices.

The older CP instances work fine (Intel Xeon) however the CPX has
an AMD EPYC CPU so I'm assuming this has something to do with the
problem.

I have attached a link to the dmesg below (had to screenshot web
console as no networking on the vm to export text).

Anyone managed to get FreeBSD running on a CPX instance?

(Note this is specifically the CPX instances - the CP instances work fine)
