Weird that it hasn't bitten many other people yet.

BTW do you have SMP / preemption enabled?  I may be missing something,
but it looks like that list_empty(&dev->driver_list) test is not
protected by a barrier from list_del_init(&dev->driver_list) in
device_release_driver().  But my understanding in these matters is less
than poor...
