Ah... new protocol. Will do. Thanks.

Commit a5bfc4714b3f01365aef89a92673f2ceb1ccf246 dropped explicit pci_intx() manipulation from ahci because it seemed unnecessary and ahci doesn't seem to be the right place to be tweaking it if it were. This was largely okay but there are exceptions. There was one on an embedded platform which was fixed via firmware and now bko#14124 reports it on a HP DL320. http://bugzilla.kernel.org/show_bug.cgi?id=14124 I still think this isn't something libata drivers should be caring about (the only ones which are calling pci_intx() explicitly are libata ones and one other driver) but for now reverting the change seems to be the right thing to do.
