Let's start with the test skip.

I am however pretty frustrated that we're really not getting anyone from 
neutron looking at this. We're at 121 rechecks (plus I'm sure there were 
plenty of no bug rechecks, I've seen a couple). So 150+ gate resets 
because of this bug. Which is 150hrs worth of delay put into the gate.
