@f32by is this something you can hit everytime, or is it hanging different each time?

It always hangs at the same position with GPU-VA enabled.

Hello @f32by
Thank you for reporting this issue, in a way it happens to be the right time for it given what I am working on.
I did not managed to reproduce this issue, and I am still not really familiar with how we approach multithreading in our code base so I need more info to make progress on that issue.

Would you be able to use a validation layer build from this branch please? https://github.com/arno-lunarg/Vulkan-ValidationLayers/tree/arno-gpu-fix-deadlock
I added some debug logs (printed in std::out) to help me track down what is happening in your case. If you could show me the logs you get, it would be very helpful.
(If need be I can output those logs to a dedicated file)
