Way to diagnose shutdown hangs?

During boot, you can hit something (escape? tab?) to switch from a graphical screen of a “wait bar” to the actual boot information being thrown at the console)

Is it possible to shut qubes down in a way that we can see the console log on the screen? (I’ve tried escape and tab (and pretty much every other button), but they do not seem to change anything (possibly because sys-usb is shutdown already))
