7.0-BETA3, Marvell 88SE6811, P35/ICH9, SATA

I have a MSI P35 Neo2 (MS-7345) mainboard. On the mainboard there are
two ATA controllers, one IHC9R SATA and one Marvel 88SE6811. I just
noticed that the Marvel 88SE6811 ATA controller has got some kind of
identification problems. It used to (beginning of november ?) be
recognized as a generic ata controller, but now (7-beta3) only rubbish
is printed in the system message buffer.

>From 'dmesg':

'pciconf -lv' identifies it as a:

...
atapci0_at_pci0:3:0:0:	class=0x01018f card=0x612111ab chip=0x612111ab
rev=0xb1 hdr=0x00

    device     = '6121 SATA2 Controller'
    class      = mass storage
    subclass   = ATA
...

Neither the DVD, nor the harddisk are recognized by the
controller. When booting from the controller, the kernel and kernel
modules are loaded, but then it seems to be unable to find disk.

I do not know if the Marvell used to work when it was recognized
as a generic controller. I never tried to use it.


The only real problem I have had with the ICH9R is that 'burncd' do
not work. However, I have been able to use 'cdrecord' together with
'atapicam'.

Since there has been some discussions regarding the P35/IHC9 - SATA, I
include parts of the output from dmesg and pciconf.

Since I only have one harddisk for the moment, I have not really been
able to test the RAID mode. It seems to fall back in AHCI mode, if I
interpret the dmesg output correctly.

The DVD are sold as an Samsung SH-S203B, and are an SATA150, if I
remember correctly. The harddisk are set to SATA300 in AHCI mode, and
SATA150 in IDE mode. In IDE mode only 4 ATA channels seems to be
recognized in the dmesg output, whereas in AHCI mode there are 6
ATA channels.
