This code makes simple systems complex:
ACPI: PCI Interrupt :03:04.0[A] -> GSI 18 (level, low) -> IRQ 16
ACPI: PCI Interrupt :00:1d.0[A] -> GSI 16 (level, low) -> IRQ 17

ACPI: PCI Interrupt :00:1d.7[D] -> GSI 23
This code makes simple systems complex:
ACPI: PCI Interrupt :03:04.0[A] - GSI 18 (level, low) - IRQ 16
