The injection was not happening at the same location as the crash reports. After using the provided disk (which was tricky), I was able to get it to work. Booting was painfully slow, and makes me wonder if there is a better way for reproducing issues in the future. I've been debating just abusing the bot to debug, but it will spam the entire list, but I have it reproducing now. Thanks, Liam
