I'm still trying to dig this...

After googling sometime I saw several reports like mine (it looks like a too
common problem). In those repots, kernel messages were a bit different from
mine. For example, from http://marc.info/?l=linux-kernel&m=119498755206823&w=2:

ata1.00: status: { DRDY }
ata1: soft resetting link
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
ata1.00: configured for UDMA/133
ata1: EH complete

Why I don't have any "SATA link up..." message ?

And at device init, some logs read like:

ata1.00: ATA-8: WDC WD2500BEVS-22UST0, 01.01A01, max UDMA/133
ata1.00: 488397168 sectors, multi 16: LBA48 NCQ (depth 31/32)
ata1.00: configured for UDMA/133

Mine is like:

ata3.00: ATA-8: WDC WD3200AVJS-63WDA0, 12.01B02, max UDMA/133
ata3.00: 625142448 sectors, multi 16: LBA48 NCQ (depth 0/32)  <===== 0, not 31 ??
ata3.00: configured for UDMA/133
ata4.00: ATA-8: ST3500820AS, SD25, max UDMA/133
ata4.00: 976773168 sectors, multi 16: LBA48 NCQ (depth 0/32)  <===== 0, not 31 ??
ata4.00: configured for UDMA/133

Just to see if I have some strange behaviour...
