There are definitely warts related to the new EH stuff, but specifically for SATA + ata_piix, it has been a long hard road of trying various probing mechanisms. Tejun has some patches that revert all the PCS work and rewinds back to original SATA ata_piix probing, in -mm for testing. If testing feedback proves positive, let's go ahead and fast-track that up the line. With ata_piix, I would worry more about PCS register follies than core libata. Users can try the module option force_pcs=[0|1|2] to experiment and see if any of the three possibilities improves their boot.
