Public bug reported:
Following #889071, I want to say that even on Kernel
linux-image-4.2.0-19-generic 4.2.0-19.23~14.04.1
(14.04 LTS with wily-kernel ) the SATA III recognition is a bit shaky, but
less than it used to be in the 3.x series.
Also, the SATA-Numbers keep changing, so it is hard to tell which disk
has the issue...:
[ 2.481536] ata8: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.481568] ata3: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.481600] ata5: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.485425] ata11: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.649406] ata7: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.481503] ata6: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
<= Thats unexpected
[ 2.501404] ata14: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 2.557461] ata13: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 3.468992] ata12: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
(about 10-20% of boots)

That's OK, but why different numbers?
[ 2.476286] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.476324] ata6: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
