I have an H67 motherboard here, and PMP is supported on all 6 ports, but only in "CBS" mode (i.e. poor performance if you try to access two drives concurrently). I'm currently wrestling with PMP support on Marvell AHCI devices.... It seems to work on an 88SE9125 with recent firmware, but not working with an 88SE9123 with older firmware. I'm planning on doing further debug later today. > ahci 0000:00:1f.2: flags: 64bit ncq sntf pm led clo pio slum part ems apst > no "pmp" in that flag list :-( Tim. -- South East Open Source Solutions Limited Registered in England and Wales with company number 06134732.
