Looks like PNP interrupt routing is broken. Check offset 0x3c in config space of your PCI devices and find what has interrupt routed to IRQ12 . Then go and check which IRQ corresponds to interrupt line used by that device (in B0D17F0 Rx55-57). Interrupt line depends on slot in which your device is inserted or assigned for internal devices. Then program correct values of IRQ in Rx3C of your device in pci_routing_fixup function of coreboot for your southbridge.
