Hi Bjorn, Thanks for your review and comments! This is my fault, I forgot we will enable pci bridges when we hot add host bridge. Push pci_enable_bridges() into the generic code is a good idea, so we don't need to consider enabling bridge in pci arch-specific code. In IA64 we don't assign the unassigned resources like other arch. This is also a weak point. I will update this patch and resend soon. Thanks! Yijing. > > . > -- Thanks!
