This tested against just fetched 4.13.0-rc2 origin/master.

Works.

Works.

Works.

Going with the suspend test, and it still leaves host dead.

Completely dead. Powerled is on, so host isn't shut down. Serial or 
network if don't give any signs of life.

Patch applies cleanly but still getting the same error:
