Issue:
When using a StarTech PEXESAT32 (also applies to the StarTech PEXSAT32), using the Marvell-88SE9128 chipset, the port-multiplier functionality does not work.
Issue:
When using the above mentioned cards, the data transfer speeds are abysmally slow. I suspect that this issue is related to, and might be a side-effect of, the first issue.

Using a Vantec NexStore dual SATA drive dock (which requires Port Multiplier functionality), the drive does not mount, and the dock shows the status light blinking at one-second intervals. This is true for both the first and second generation versions of this dock. The dock works perfectly well on another computer using different eSATA cards.
Single-slot docks, or single-drive HD enclosures, do not have this issue. However, the transfer rate is abysmally slow.
This system, using these eSATA cards, does not have this issue, depending on the operating system installed.

Pci Express X1 Slot

1. Windows 7 et. al. do not have this issue as there are drivers that can be installed.
2. The Acronis True Image 2012 Home Premium stand-alone CD, which runs an unknown distribution of Linux, can access the drives within this dock.
3. Knoppix 7.6.0 (Based on Debian), is able to mount this device. There are issues where the device mounts, reads, falls off, resets, and remounts repeatedly - but at least it works to some extent.
Other Linux distributions fail:
1. Mint, from 13 onward, fails. (I have not tested versions prior to 13.)
2. The Avira Rescue Disk - which is based on Ubuntu - fails.
3. Fedora 23 Workstation also fails.
I have not tested any other distributions.
Marvell's web site, (http://www.marvell.com/storage/system-s ... /index.jsp)
claims that the 'AHCI standard inbox driver' is what is required, and is (supposedly) pre-compiled into the kernel.
However. . . .
There is some interesting documentation within Ubuntu's fora, on the HighPoint RocketRaid SATA/eSATA cards which use the same chipset, located at:
http://ubuntuforums.org/showthread.php?t=1725828
which contains a reference to:
https://help.ubuntu.com/community/RocketRaid
which describes a way to compile a patched kernel that supports (at least) the RocketRaid boards. Translation: It's not

in the kernel? Or, perhaps, because it does/can work within Knoppix/Debian, maybe there is a regression that has been introduced somewhere within the Ubuntu distribution chain?
This leads me to believe that it is a problem with the operating system's ability to interface with the card, and not the underlying system hardware that the card is plugged into.
Does anyone have any other ideas about this?
Thanks!
