AMD bettong: Fix the interrupt routing.
The plugged devices on PCIe should use IOAPIC2 instead of standard IOAPIC1. The entries in IOAPIC2 count from the end of IOAPIC1. The unchanged code worked because the OS uses MSI instead APIC. To test that, boot linux with parameter pci=nomsi and see if the devices like NIC work well as they do without the booting parameter.
