Hi all,

I'm throwing this out here in the hopes that someone smarter than me has
a simple solution - never hurts to be optimistic. :)

I have a HighPoint controller, RocketRAID 2320 (8-port PCIe SATA  
fakeraid). It is only supported by an ugly binary blob deceptively  
labeled as an "open source driver" from HighPoint (rr232x). Looking 
at the wrapper around the blob, it seems this driver claims only 
the 2320 and 2322 controllers:

static const struct pci_device_id hpt_pci_tbl[] = {
        {PCI_DEVICE(0x1103, 0x2320), 0, 0, 0},
        {PCI_DEVICE(0x1103, 0x2322), 0, 0, 0},
        {}
};

I've found that this controller contains a marvell 88SX6081 chip, which
should be supported by the sata_mv driver. That driver claims device IDs
2300 and 2310:
        { PCI_VDEVICE(TTI, 0x2300), chip_7042 },
        { PCI_VDEVICE(TTI, 0x2310), chip_7042 },

So, ever hopeful, I tried adding the 2320 into the table:
        { PCI_VDEVICE(TTI, 0x2320), chip_608x },

When I do this, the kernel successfully probes the attached disks and
their capacity, but immediately errors out and starts resetting the
ports repeatedly.

..

Send me a clear, in-focus detailed photograph of the board,
showing the chip markings very clearly.

Never mind -- found one here:

The SATA chip is clearly a 88SX6091-8CZ, which is a PCIX 8-port controller.

                            ^^^^^^^^
That was supposed to say 88SX6081 there.  :)

Ah, I see. I hadn't checked the datasheet, but it is indeed.

Since it is sitting on a PCIe card, one must assume there's a PCIe-to-PCIX
bridge hidden under that huge heatsink.

So if the card does not work in the chip_608x mode,
there's probably some funny business in that bridge chip.

Maybe it works *only* in the proprietary RAID mode (?)

I found some better chip pics (minus heatsink) here:
http://www.pcdvd.com.tw/showthread.php?t=788031&page=3&pp=10

It shows that under the heatsink is an Intel QG41210 serial-to-parallel
PCI bridge. I found it's datasheet here:
http://www.intel.com/design/bridge/datashts/27887505.pdf

Hope this helps. :)

Is there any more debugging information I could send that could help
diagnose this?

..

How about "lspci -vv", to go with the other info.

Then, perhaps Saeed Bishara from Marvell could have a peek ?
I'm on holiday for the next week and a bit, and Marvell is in arrears
for earlier work on this driver.

Cheers
