I change the IRQ in the pci_irq_map[] with the value GPIO2IRQ(11) and
also change the MPP setting then compile with option pci, but freeze
at the same point. 

At this time I refer to the following:
http://fxr.watson.org/fxr/source/arch/arm/mach-orion/kurobox_pro-setup.c?v=linux-2.6
http://fxr.watson.org/fxr/source/include/asm-arm/arch-orion/irqs.h?v=linux-2.6


Maybe KBP has a PCI Express connector but doesn't have any other PCI
connector, Is this related to the problem?
