Thanks very much for testing this.  Can you collect the complete
dmesg please?  We need the information about the host bridge
windows and the device that we assigned resources to, and the
snippet you included doesn't have that.

If you're able to boot Windows and collect an Everest report
(http://lavalys.com), that would be a great bonus.  The goal
is to allocate things the same way Windows does, but obviously
I failed somewhere.
