Dear All,

After I've upgraded from kernel 3.4.X to 3.10.14 and I noticed 2 drives 
missing that
are connected on Marvell 88SE9172 SATA Controller.

The last version that worked properly was 3.5.7, but any kernel above 
3.6.0+ drives connected to Marvell are missing.

This was tested on Board GA-X79-UD5 
http://www.gigabyte.com/products/product-page.aspx?pid=4049#sp
that have 3 x Marvell 88SE9172 chips.

tested kernels:
linux-3.10.1.tar.xz   linux-3.12-rc3.tar.xz  linux-3.6.11.tar.xz 
linux-3.7.10.tar.xz
linux-3.10.14.tar.xz  linux-3.4.64.tar.xz    linux-3.6.5.tar.xz 
linux-3.8.13.tar.xz
linux-3.11.3.tar.xz   linux-3.5.7.tar.xz     linux-3.6.tar.xz 
linux-3.9.11.tar.xz

3.6.0+ dmesg:
