Re: IDE diriver error message as "hda: lost interrupt"



Of course, all the INTRQ- and DMARQ-pins (0..3). are pull-downed
and cable is cut less than 10cm.

But result is all the same.
Data and control signal input and output are all right.
It's tested and monitored as bit by bit.

I don't know what's the reason of trouble..
