Bleeding-edge 12.0 issue? > Poked around at this a bit more and found a workaround. It seems FreeBSD doesn't support the latest default PPC machine in qemu. Available options are listed below. After switching from the default pseries-2.6 to pseries-2.5, FreeBSD 12.0 works flawlessly. I attached a script I'm using to install and then boot the VM. So now there's an easy way to test/fix ports for PPC64. Runs about as fast as a 486, but that's fine since we can install dependencies via "pkg install" to reduce build time.
