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.

I've attached a dmesg output. I can provide any further debugging info
or try different things.

I've tried defining the controller with chip_6042, chip_604x and
chip_7042 with no success.

PS: Please CC me on replies, as I'm not subscribed to linux-ide.

Kind regards,
