>Description:
The Plextor M6e PCI-E SSD is a relatively new device, but it uses the Marvell 88SS9183 controller.  This controller was added in revision 254987 to support the 2013 Macbook Air.

After a camcontrol rescan all I get this error:

(aprobe0:ahcich0:0:0:0): Unexpected signature 0xffff

pciconf for the Plextor M6e:
