Something unrelated to the tests I am doing.

I found out that the libsata driver doesn't really cope or likes the
idea that you might have a controller without a master drive
configured.

In this case on ATA2 I have a CDROM drive, connected as slave.
ATA: abnormal status 0x7F on port 0x177
ATA: abnormal status 0x7F on port 0x177
ata2.01: ATAPI, max UDMA/66
ata2.01: configured for UDMA/66

Having a single drive on the channel configured as slave is not really a legal configuration. (I believe the ATA standards say that it's something that a host controller/driver/OS is allowed to support, but it is not required to.) A single drive should always be set to master (and connected to the end of the cable and not the middle, by the way).
