The later kernels will drop the SATA speed on repeated errors if they see what appears to be a consistent problem that might be cabling/noise. > Is it possible to set the SATA link speed somewhere? Not sure. I've not looked whether that is in the new "force" code. I don't think you can in 2.6.24 however, and 2.6.25 will fall back nicely. Other than being annoying during the install it should not cause any other problems beyond all the retries.
