Comment 3 for bug 1286979

From the dmesg, I found the disk (sda) is a SATA 3 disk, the ahci driver will cover this kind of disk. While all errors were reported from sas driver (serial scsi driver, intel isci driver). so from my point of view, it is not a big problem since we don't have a sas disk installed on the machine.

I don't why sas driver will send command to a SATA disk, maybe latest kernel already fix it. It is worth to install a 3.13 kernel to test again.
