I noticed that since I started using 4.6.0-rcX, my screen flickers once or twice after I stop using my laptop for ~1min or so. Given the behavior, my prime suspect is the PSR feature that you have announced for this release:

Is 'enable_psr' the right knob to use to turn this feature off and see if my suspicions are correct? Or is there a patch floating around that I can test?
i915.enable_psr=0 is the one to try, yes.
I can confirm that with PSR off, the flicker goes away.
Please file a bug at [1] and assign to Rodrigo (Cc'd).
