I haven't had a fully successful StR cycle yet (in 5 tries), although I
can't pin them all on RCU. On try 2 it hung completely about 10 seconds
after I unlocked the screensaver, on try 3 it came back to a black
console, and on try 4 it didn't suspend at all (blinking moon LED but
battery LED and CPU fan still on).
