The code is generic enough, i think it should work. We only found this issue because it hangs with one of our customers with resizable bar enabled and with a big graphic card, so I dont think I can reproduce it on our side as I dont have the hardware setup. This is actually found by Benjamin, that edk2payload should also have the resizable bar flag enabled or else there might be something wrong with the resources allocation.
