It works just fine. I'm just a little concerned about the
capabilities. Comparing with the JMicron controller:

ahci 0000:02:00.0: AHCI 0001.0000 32 slots 2 ports 3 Gbps 0x3 impl SATA mode
ahci 0000:02:00.0: flags: 64bit ncq pm led clo pmp pio slum part

It would seem that something else is going on with the ICH8 controller:

ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 4 ports ? Gbps 0x33 impl SATA mode
ahci 0000:00:1f.2: flags: 64bit ilck stag led pmp pio
