sata_mv (Supermicro DAC-SATA-MV8 controller) does not load on dapper, works in edgy

[George Wright]

The sata_mv driver in the default Dapper kernel does not work with this controller. I believe the driver started working with this card after release 2.6.16 of the kernel - I can confirm it works with release 2.6.17.8.

Can you provide the PCI ID, using:

  lspci -n

of the SATA controller. You said IRC there was some message about "failing to set argument", can you confirm this message.

IIRC, You also mentioned that you had tried backporting the driver that from 2.6.16 and that it required backporting the whole ATA stack aswell.

[George Wright (gwright)]

The message it says is:

[ 217.977449] ata13: failed to set xfermode, disabled

As for backporting - yes, the entire ATA stack needs to be backported as they introduced some new stuff which the driver uses in versions > 2.6.15

lspci output:

Well, we aren't going to be back porting the entire libata stack to 2.6.15, so if you can find some specific commits to this driver that enabled it to work with your device, then I can backport those individually.

I changed the description line. It had referred to the product as "DAC-SATA-MV8" when in fact
the correct product number is OAC-SAT2-MV8, per the supermicro website and many online
retailers.

For the sake of those searching, I would also note this board is built on the Marvell 88SX6081
controller.

Has there been any success getting this board to work (just as a controller, I'll handle
the RAID stuff in software) in Dapper?

It is not the OAC-SAT2-MV8. The DAC-SATA-MV8 is the predecessor to the OAC-SAT2-MV8 which was a SATA-150 controller, instead of SATA-300 which the OAC-SAT2-MV8 is.

Here is the lspci output for the board:

Sorry George, and everyone being bothered by notifications of my changes. I poked at the supermicro site a fair bit before convincing myself there was an error in the model number. I've changed things back.
