Hello,

my laptop has an Intel 82371AB USB Host Controller which gets irq
128 assigned.
The Interrupt Router Intel 82371FB PCI-to-ISA Bridge (PIIX) issues a
warning:

000:07:2 0x8086 0x7112   D  0x03   5  2    WARNING: preserving irq 128

Is it possible to configure a reasonable irq for this device?

-Hanspeter
