Sorry.  I forgot to mention the situation.

While I was using Max40 and Max60 on IDE3, no problem.  I
added DJNA to IDE4-1, I lost interrupt on IDE3-1 (Max40).  I
moved Max40 to IDE-1, then I lost interrupt on IDE3-2
(Max60) twice.  I moved both Max40 and 60 to IDE-1, then I
lost interrupt on IDE1-1 (Max40) twice.  These are all 5
hangs which I experienced last night.

I've never gotten problem on DJNA connected line although
this problem appears when I add DJNA.

Ok.  I'll try to such configuration using 2 drives on 2
UDMA66 channlels.


In addition, I'm using a SCSI drive through AHA2940UW.  I
got these hangs from a kernel with and without RAID_FRAME
option.
