I sent the related dmesg lines, and my .config.
for dmesg and .config :
http://marc.theaimsgroup.com/?l=linux-kernel&m=111179215521092&w=2

what part of lspci would you need ?

hdparm :

flash@evenflow:~$ sudo hdparm -i /dev/hda

/dev/hda:

 Model=Maxtor 6Y160P0, FwRev=YAR41BW0, SerialNo=Y47J8CRE
 Config={ Fixed }

 IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes:  pio0 pio1 pio2 pio3 pio4

 UDMA modes: udma0 udma1 udma2 
 AdvancedPM=yes: disabled (255) WriteCache=enabled
 Drive conforms to: (null): 

 * signifies the current active mode

(it shows no mode... it's strange, because this drive should be nearly
the same as the following)

flash@evenflow:~$ sudo hdparm -i /dev/hdc

/dev/hdc:

 Model=Maxtor 6Y120L0, FwRev=YAR41BW0, SerialNo=Y31LWCXE

flash@evenflow:~$ sudo hdparm -d /dev/hdc

/dev/hdc:
 using_dma    =  0 (off)

(Note : hdparm -i says 'udma6', and hdparm -d says 'no dma'...
Strange, isn't it ?)

I'll try that...

I succesfully used these drives with another motherboard (PIIX4)
before, in udma2 mode, for years...

But first thing : I have to check if the cables are correctly plugged
in (I mean in the correct order)... I didn't have the time to do that
yet.

Thanks for your answer.
