If you are getting an oops there, it looks like your ata_piix driver is 
mismatched from the libata core.  Did you compile them both at the same 
time, from the same source kernel?

The assembly code above is where function ata_host_add in libata-core.c 
calls "ap->ops->port_start", which definitely exists in ata_piix.c.
