SATA: link online but device misclassified

SATA: link online but device misclassified

[Marc Bowes]

Greetings,

Firstly, I hope that the SCSI list is the correct place to ask about SATA.

I just got a new chipset (Gigabyte EP45-DQ6) courtesy of a
competition. This coincided with the death of a hard drive. I had to
reinstall my Gentoo system on the new hard drive, and hit this issue
when booting the newly configured Kernel (2.6.29-gentoo-r5):

ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1: link online but device misclassified, retrying
ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1: link online but device misclassified, retrying
ata1: link is slow to respond, please be patient (ready=0)
ata1: softreset failed (device not ready)
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1: link online but device misclassified, retrying
ata1: limiting SATA link speed to 1.5 Gbps
ata1: softreset failed (device not ready)
ata1: SATA link up to 1.5 Gbps (SStatus 113 SControl 310)
ata1: link online but device misclassified, device detection might fail
ata2: link is slow to respond, please be patient (ready=0)
ata2: softreset failed (device not ready)
... (as with ata1)

This whole process takes a very long time (minutes) to finish. It
seems to be down-grading two of the four SATA-2 drives to SATA-1
speeds. The drives are actually SATA-2 drives, and appear to work (at
full speed) on my Windows 7 install.

Please advise.

Best,
Marc

Not really, linux-ide is the preferred place.

What drive model, what ATA controller, and have you checked you're really
getting 250MB/s under Windows?

Hi,

The drive I just bought:
SEAGATE 160GB SATA 7200RPM HDD

The other is a Western Digital 500GB.

The ATA controllers: Intel Corporation 82801JI (ICH10 Family) 2 port
SATA IDE Controller.

To be honest, I'm not even too concerned about the link speed, I'm
more annoyed by the long timeout at boot time.
