Looks like when I tried to pass the GPU it was in the same group as the USB controller my unraid boot stick was in causing the crash. Moved the USB drive to another port and it no longer crashes everything. Unfortunately I still only get amd-vi completion-wait loop timed out when trying to passthrough the on board GPU.

While trying to boot any VM and selecting the on board Vega graphics as pass-through I see this over and over in the log and the WebGUI crashes and resets and is unresponsive. I have tried Win 10 and Arch.
