Hmm... it could be that the multiple msix routing gets screwed when the bios disables unoccupied ports. Dan, can you please look into this? Shah is seeing ahci failing during boot on an AMD platform with msi enabled. If disabling of unoccupied ports is turned off in bios, the problem goes away. Maybe we're mapping the irqs incorrectly in such cases?
