SATA III recognized as SATA II

[Grizzly]

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)
[ 2.476356] ata3: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.476386] ata5: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.476409] ata4: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.480199] ata11: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[ 2.500201] ata13: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 2.500229] ata14: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 3.303818] ata12: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

That is on Asus Sabertooth AMD-FX8350-Board.
