Hi all,
According to PCI 3.0 spec, ACHI's PCI class code is 0x010601,
and I suggest the ahci driver had better try to claim all ahci
controllers, pls see the following patch:

Since things have settled in this area, yes, this would probably be a
good thing to add.
For the benefit of others, some background: we should not be -removing-
any PCI IDs due to this, because quite often the PCI class code will be
RAID or something else, yet still be drive-able with this ahci driver.
