This happens because satapmpinitlinks() initialize link->pmp up to SATAPMPMAXPORTS while empriv is declared as 8 elements array.

I can't find the maximum Enclosure Management ports specified in AHCI spec v1.3.1, but "12.2.1 LED message type" states that "Port Multiplier Information" can utilize 4 bits, which implies it can support up to 16 ports. Hence, use SATAPMPMAXPORTS as EMMAXSLOTS to resolve the issue.
