Hello,

It seems that FreeBSD 12.0-ALPHA4 is having trouble booting on KVM on 
POWER9 (Talos II).

Here's the image I've tried: 
FreeBSD-12.0-ALPHA4-powerpc-powerpcspe-20180831-r338410-disc1.iso

It fails regardless of whether I run kvm from the console or through 
virt-manager.

Seems to be disk related... I get the messages below regardless of 
whether I try to boot from CD-ROM or disk. I've tried all disk types for 
both (usb, scsi, sata, virtio, etc).

It's important to note that this worked on an older snapshot of 
12.0-CURRENT, though I don't know the last specific working revision I 
tried.

Here's the output:
