So are you saying the ESB2 spec is violating a higher level spec? I know almost nothing about AHCI, so please forgive that question... >What status values are you seeing?

This is output from our SLE10SP2 kernel, the output is similar for others: <6>scsi2 : ahci <6>ata3: SATA link down (SStatus 0 SControl 300) <6>scsi3 : ahci <6>ata4: SATA link down (SStatus 0 SControl 300) <6>scsi4 : ahci <6>ata5: SATA link down (SStatus 4 SControl 300) <6>scsi5 : ahci <6>ata6: SATA link down (SStatus 0 SControl 0) Even the message relating to ata5 seems a little dubious to me, as it's not in sync with what the other unused ports say (and also not in sync with what I see on other boxes - SStatus is always 0 for such ports).
