Yes latest hdparm-7.7. But maybe it is related to git kernel? Cause lines
[    8.658485] hda: applying conservative PIO "downgrade"
[    8.674009] hda: host max PIO4 wanted PIO255(auto-tune) selected PIO0

appeared only in those kernels (2.6.24-git/rc)


Anyways:

WRAP ~ #./hdparm --Istdout /dev/hda
