Ahh.. perhaps because it doesn't fix the problem I'm seeing here. Oh well, anyone else got a fix for this regression yet? Even doing a rescan-scsi-bus doesn't work on the closed down ports. Basically, any unoccupied AHCI port is dead to the world after a simple suspend/resume (RAM) cycle. On one of my machines I can hot unplug/replug the ExpressCard adapter to recover, but that doesn't work so well for built-in SATA/eSATA ports.
