You still haven't mentioned what devices you are using. The problem is most certainly related to the type of drives/devices as the 1742 and 2742 code is completely different. I have both of these cards (my 2742 is dual-channel), and have used a 1742 extensively with no problems. Under old snaps, the 2742 used to hang under heavy load, but I found this to be fixed a couple of weeks before 2.0.5R. Under both of these cards I can run multiple parallel "iozone"s to multiple drives without a problem (which is the heaviest disk load that I can simulate). Tom
