Marvell 88SE6121 not supported

[Stephen Hemminger]

Binary package hint: linux-image

The Marvell 88SE6121 SAS disk controller on Asus P6-T motherboard is not supported in Jaunty.
It appears to be as simple as just enabling CONFIG_SCSI_MVSAS=m in kernel config!

As far as I know, the mvsas driver is for 88SE6440 devices. If you need to enable SATA support on a 88SE6121 device, you can learn more at http://wiki.debian.org/pata_marvell.

If you think this is still a bug, please include the following additional information:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

Marvell devices on ASUS P6-T are:

Just enabling CONFIG_SCSI_MVSAS gets the correct driver.
I even extracted driver from kernel source and built it standalone, and that worked as well.

  Kernel 2.6.28-12 (which is now in jaunty's proposed-updates) adds support for mvsas:

uname -a
Linux gre019099 2.6.28-12-generic #43-Ubuntu SMP Fri May 1 19:31:32 UTC 2009 x86_64 GNU/Linux

 find /lib/modules/ -iname *mvsas*

i followed the instructions on http://wiki.debian.org/pata_marvell and now my two disks are being detected as /dev/sdc and /dev/sdd. however, i have them setup in a RAID-1 using the Marvell option ROM , in the BIOS. so, shouldn't linux see it as one device? does that mean i am a victim of this bug?

i am using ubuntu 8.10 with linux 2.6.27-14-generic. i actually have the 88SE6121, so i am confused by Stephen Hemminger's comments regarding the 6440. i notice in lspci it says the controller is using the 'ahci' kernel module, shouldn't that be raid or something?
