I have tested the lasted kernel located here : http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-rc1-oneiric/ and named : linux-image-3.2.0-030200rc1-generic_3.2.0-030200rc1.201111071935_amd64.deb
The sata is always limited to something about 308Mo/s. palimset indicates me that thing about the controler : "6 series/C200 series chipset familly 6 port SATA AHCI controler". Noting about the SATA I, II or III. As you tell me, I have removed 'needs-upstream-testing', and added the tag 'kernel-bug-exists-upstream'.
