For some reason, a PHY event is being reported after reset is complete which unfortunately gets reported while DIPM command is in progress. Hmmm... what's broken is that the PHY event happens after reset is complete. Can you please attach the output of "lspci -nn" and "hdparm -I /dev/sda"? Looks a lot like a timing issue. Maybe we'll have to add a delay somewhere. :-( -- tejun
