Command switching PMP support is merged for 2.6.24 too. Many (if not most) vendors now use ahci as programming interface for storage controllers, so ahci driver supports lots of controllers from many vendors. Bugginess depends on which vendor or chip you're actually using but in general all are well supported and if you report a problem, it's very likely to get fixed soon. * sata_sil: 3112 chips have problem with early seagate drives but both 3112 itself and those drives have been discontinued for a long time now. There are reports of data corruption when 3114 is connected to mobos with NVidia chipsets. This is still being investigated. If you're on intel mobo, 3112/3114/3512 should work good. * sata_sil24: 3124/3132 chips don't have any outstanding serious problems. IRQ loss on PCI-X was the only recent serious known problem but it's fixed now. These chips are pretty advanced and all the advanced features are supported by Linux including FIS switching PMP support (will be included in 2.6.24 release); however, there is a known hardware performance limitation so you can't use full SATA bandwidth even if you use PMP but it's more than sufficient for most cases and this chip is my personal favorite. * sata_promise: Generally works okay; however there are still some problems with recent 3Gbps chips.

But right now it is rather spotty. I don't know much about the other Marvell chips that run under AHCI, but I hear that they're just fine.
