I was able to reproduce these failures locally on the ember-release track using this command:

$ ember try:one "ember-release" --skip-cleanup=true --- node_modules/.bin/ember test --filter="Ember Debug"

Yes, we know about these failures. There were changes in Ember we have not fixed things for yet.
