I'm a little surprised that no one else has encountered this. I was experiencing intermittent errors when trying to deploy an image to a controller. More often than not, deployment would report an incompatible chassis. In the RAD source, I tracked it to a bug in the function that extracts the system image to the user's local temp folder. There is parallel execution where a folder path is deleted while at the same time files are attempted to be copied to that location. Making these operations sequential seems to resolve the issue.
