I had already done that yesterday.
Shortcutting the device_quiet() doesn't help at all.

The device_printf() was something I didn't try yet.  Combined with BUS_DEBUG
still in my kernel it yields:

devclass_find_internal:115: looking for nexus
devclass_add_device:404: (null) in devclass nexus
devclass_alloc_unit:353: unit 0 in devclass nexus
devclass_alloc_unit:393: now: unit 0 in devclass nexus
root_bus_configure:2309: .
devclass_find_driver_internal:253: nexus in devclass root
device_probe_child:641: Trying nexus
nexus0: nexus_probe()

After that it kernel trap 12's.
