An enhanced (compared to original PC/AT) interrupt controller. An ioapic
is necessary for SMP support and should also improve interrupt
distribution on single CPU systems.

It apparently causes interrupt routing issues. You could try one of
these options:

# PCI fixups, for both PCIBIOS and ACPI
#options        PCI_ADDR_FIXUP          # fixup PCI I/O addresses
#options        PCI_BUS_FIXUP           # fixup PCI bus numbering
#options        PCI_INTR_FIXUP          # fixup PCI interrupt routing

"PCI_INTR_FIXUP" could e.g. solve you problems. Another option is to
update the BIOS of your machine.
