No! :-)

it found a pre-existing suspend+resume breakage on a testbox. (I.e. the 
debug patch worked as i'd expect it to work. Every good debug patch 
starts its lifetime with a sharp spike of breakages it finds.)

( my kernel test-setup does in excess of 100,000 random kernel bootups 
  per year and me not having to hit the keyboard or close+open the lid a 
  hundred thousand times, day and night, to find the occasional 
  suspend+resume regression is a not to be under-estimated plus. )
