Cable detection on nv controllers are broken. We tried a lot of things but
nothing worked reliably. The current code at least seems to avoid mistaking
40c cable to 80c although it often does the reverse.
Currently, the suggested way to fix the problem is just to take what the BIOS
has configured. There have been some resistance against this approach as it
doesn't really work on non-x86 machines (theoretical possibility yet), may have
some problem over suspend/resume and hotplug (again, theoretical). Anyways,
it's been agreed that there doesn't seem to any other way.
This 'agreement' happened post 2.6.22 and thus sata_nv currently doesn't
contain the code. I'll see whether I can port the fix.
Thanks.
