Oh, looking at that commit that might make sense. In ahci_host_activate_single_irq it now uses dev_driver_name instead of dev_name as it did before (from ata_host_activate). The description sounds like before the driver is registered this will return the bus. And registering an interrupt would likely be before the driver is fully registered... But you probably saw that, too. Whether that really was intentional is still the question. :) -Stefan > > -- > Sander > > > /proc/interrupts of an ahci controller with a single irq: > 52: 13529 0 0 0 xen-pirq-msi > 0000:00:1f.2 > > /proc/interrupts of an ahci controller with multiple irq's: > 114: 412535 0 0 0 0 0 > xen-pirq-msi ahci0 > 115: 0 0 0 0 0 0 > xen-pirq-msi ahci1 > 116: 16717 0 0 0 0 0 > xen-pirq-msi ahci2 > 117: 0 0 0 0 0 0 > xen-pirq-msi ahci3 > 118: 0 0 0 0 0 0 > xen-pirq-msi ahci4 > 119: 0 0 0 0 0 0 > xen-pirq-msi ahci5 > >
