Ok. The error happens in the call of pcibios_enable_device in the function do_pci_enable_device (drivers/pci/pci.c): Before the call of pcibios_enable_device: do_pci_enable_device: pci_dev= c1a40000 do_pci_enable_device: irq= 218 do_pci_enable_device: msi_enabled= 1 after the call: ACPI: PCI Interrupt 0000:00:1f.2[B] -> GSI 19 (level, low) -> IRQ 19 do_pci_enable_device: pci_dev= c1a40000 do_pci_enable_device: irq= 19 do_pci_enable_device: msi_enabled= 1 So the function acpi_pci_irq_enable in drivers/acpi/pci_irq.c needs to be fixed: a.) acpi_pci_irq_enable should care about msi setups and set the flag msi_enabled to 0 or b.) acpi_pci_irq_enable should care about msi setups and should touch the dev->irq field.
