Jack, any insights with regards to this patch? This also touches on what Adrian was mentioning as well, at least to some degree. I have a slight modification to John's earlier changes, namely, it masks the full EIMC register when setup to use MSIX, I'm thinking this might be why the earlier patch failed? The code in this latest email is something that I would not want to use if possible, it's just trying to avoid the problem. Please test with this change instead. Regards, Jack
