++ * It has been observed with some SSDs that the timing of events in the
++ * link synchronization phase can leave the port in a state that can not
++ * be recovered by a SATA-hard-reset alone. The failing signature is
++ * SStatus.DET stuck at 1 ("Device presence detected but Phy
++ * communication not established"). It was found that unloading and
++ * reloading the driver when this problem occurs allows the drive
++ * connection to be recovered (DET advanced to 0x3). The critical
++ * component of reloading the driver is that the port state machines are
++ * reset by bouncing "port enable" in the AHCI PCS configuration
++ * register. So, reproduce that effect by bouncing a port whenever we
++ * see DET==1 after a reset.
