Hi Garrett,

I'm not strictly a PPC developer, however I do spend a lot of time 
developing and testing OpenBIOS for SPARC and as part of this tend to 
test various PPC images to ensure that no regressions are introduced.

As you noted FreeBSD-ppc gets fairly far these days; I can imagine that 
you're either seeing an issue with properties on PCI devices or possibly 
a bug in machine emulation. Can you share the command line you are using 
to launch QEMU?

While I don't have the ability to look at this myself, I suspect anyone 
with a debug PPC kernel setup would be able to find the issue fairly 
easily. I tend to be around on the qemu-ppc list so if anyone is 
interested enough to participate, please start a thread there and I'll 
pick it up there.


ATB,

Mark.
