Index: linux-2.6.29-rc2/drivers/pci/pci.c =================================================================== --- linux-2.6.29-rc2.orig/drivers/pci/pci.c +++ linux-2.6.29-rc2/drivers/pci/pci.c @@ -1453,7 +1453,7 @@ u8 pci_common_swizzle(struct pci_dev *de { u8 pin = *pinp; - while (dev->bus->self) { + while (dev->bus->parent) { pin = pci_swizzle_interrupt_pin(dev, pin); dev = dev->bus->self; }
Current pci_common_swizzle() seems to have a assumption that pci_bus->self is NULL on the pci root bus. But it might not be true on some platforms. Because of this wrong assumption, pci_common_swizzle() might cause endless loop. We must check pci_bus->parent instead.
