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.

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.
