Recompiled only the driver after modification and the output is:

I don't think that this is really what you wanted - you probably 
wanted the place in libata where insmod stops, but the root FS is on 
another SATA disk connected to the ICH6, so if I enable DEBUG for 
libata this controller/disk will log quite a lot, right ?

I'll try, but this requires recompiling the kernel. But I'll wait for 
the confirmation on whether the whole libata should be DEBUG-ed before 
starting the recompilation.
