 Patch managed to get 2 out of 4 drives up; or 3 out of 5 if we count the
 ghost-device at port 7:
 
     ahcisata0 port 0: device present, speed: 6.0Gb/s
     ahcisata0 port 1: device present, speed: 6.0Gb/s
     ahcisata0 port 7: device present, speed: 1.5Gb/s
     ahcisata0 port 3: device present, speed: 6.0Gb/s
     ahcisata0 port 2: device present, speed: 6.0Gb/s
     ahcisata0 channel 2: clearing WDCTL_RST failed for drive 0
     ahcisata0 channel 3: clearing WDCTL_RST failed for drive 0
     wd0 at atabus0 drive 0
     wd0: <Samsung SSD 840 EVO 500GB>
     wd0: 465 GB, 969021 cyl, 16 head, 63 sec, 512 bytes/sect x 976773168 sectors
     wd1 at atabus1 drive 0
     wd1: <WDC WD60EZRZ-00GZ5B1> 
     wd1: 5589 GB, 11628021 cyl, 16 head, 63 sec, 512 bytes/sect x 11721045168 sectors

 So rootfs is up but since wd[23] are missing, rf setup fails.

 In the adapter-BIOS, I see:
 
     "HBA 0: Marvell 0"
      -> "Configure SATA as: AHCI Mode"
 
 
 (I just checked netbsd-7, same issue)
