full dmesg of my affected system
Starting with kernel 3.15 Marvell SE91xx SATA 3 controllers are not getting
recognized correctly. At early boot process, users get messages similar to
this:
kernel: ata16: EH complete
kernel: ata16.00: configured for UDMA/66
kernel: ata16: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
kernel: ata16: hard resetting link
kernel: ata16.00: cmd a0/01:00:00:00:01/00:00:00:00:00/a0 tag 2 dma 16640 in

kernel: ata8: SATA link down (SStatus 0 SControl 300)
There seems to be a high rate of users affected, and so far this issue can be
reproduced with SE9129 and SE9130 chips, see
