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.

Thanks.
