General comment: I don't have code+specs+testbox in front of me, so I can only offer general [from the airport :)] advice: Under AHCI particularly, -not- disabling some power management modes has the effect of making runtime power management _too_ aggressive, leading to either a too-often parking of heads, or aggressively blinking the link, which sometimes causes COMRESET to be issued too often. So libata has followed the general policy of always disabling runtime power management. This is _not_ a rule, just a starting point. Changes are welcome...... after those changes are verified to not have negative effects.
