Marvel SAS 6440 not supported, missing mvsas module in kernel

NB: The issue is the same for the -generic and -server kernels. The -generic is more important to fix as it is used for the installer cd/dvd images.

Thanks vincefn,

It does indeed appear this is not enabled. Will try to ping the kernel team. Thanks.

If you make this modular, please remember to add it to an appropriate udeb for d-i.

SRU Justification

Impact: Enables SAS drives on motherboards usning the Marvel adapter
Patch Description: Change MVSAS configuration option to enable the use of the driver.
Patch: attached

Test Case: See bug description

Accepted linux into jaunty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Package linux-image with SAS support still unavailable in jaunty-proposed (or in which package it placed?).
But I tried to compile kernel with this patch - it works fine.
SAS disks and raid on SAS also works.
I use ASUS P6T motherboard with marvell 88SE6320 SAS controller.
The only comment - dmraid does not start automatically, fsck died on boot,
needs to be done in the root-console:
dmraid -ay
mount -a

I test linux-image-2.6.28-12-generic (AMD64) on motherboard ASUS P6T - SAS RAID works good.

   I can confirm that 2.6.28-12 (which is now in jaunty's proposed-updates) fixes this issue.

    It would be nice to have this kernel for the installer CD/DVD images too.

Should this fix allow me to mount a SATA RAID array with this controller? I've made the update and still can't see my array.

  The question is: does the mvsas module actually support hardware raid ?

  You may want to ask the modules' author. Apparently most people under linux use software raid which is quite good.

This is probably beyond the scope of this bug fix, but I turned hardware raid off and still can't see my drives. If I plug one into the intel SATA controller it works fine.

I misread your first message - yes it is defintely beyond the scope of that bug fix, because you want SATA, not SAS.

Have you looked at: http://wiki.debian.org/pata_marvell ?

Another person (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/335615) used that paged and managed to see its sata disks, though not with raid.

This bug was fixed in the package linux - 2.6.28-13.44
