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
# 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.
