Are you sure ata7 is an unused port? I'm pretty sure there must be a
drive on that port and it's throwing errors on writes. Can you post
the full dmesg log?

Hello Robert,
Indeed I am sure.
The lsscsi output says so:

Physically there is only one used port.

Relevant parts I can see:
Ouch! you are correct!
Ata7 is scsi6 that is where the disks are connected!

So I am in trouble here.
I have downloaded, configured and I am ready to install Linux-3.2.4 if
that might help.

Looking at the output a bit more closely, it seems a bit strange. The 
controller is reporting failures to send a command FIS, and also 
supposedly seeing uncorrectable errors from the drive. You could try a 
later kernel but I suspect this may be some kind of hardware issue. 
Maybe some kind of SATA cable problem?
