Actually this "port frozen" thing was already resolved.. it's supposed to be
like that. 

Port names are initialized with -1 as a default, and only given real
numbers/names later in the initialization process.

That initialization never happens in ata_piix driver because
devm_request_irq() fails and initialization is skipped with pv_ops dom0
kernel..
