Can't capture ADS image with 6i Controller

[CA1256757]

I am using Microsoft ADS (Automated Deployment Services) to capture images of Proliant Servers. This works great on DL360s and DL380s G2s and G3s. After updating the ADS deployment agent with the latest 6i drivers I am able to Boot-to-DA but I cannot capture an image. When I call imgbmdeploy.exe I get "Failed to read volume". Has anyone successfully used ADS to capture an image of a Proliant server with the new 6i controller? I am suspecting there is a bug in the way imgbmdeploy.exe and the drivers for the new 6i controllers communicate with each other. Anything I have with the 5i controller works fine.
