Did you have two screens when testing?

I guess that means the bug is not really bisected.
I started debugging the bcs-flip-vs-dpms failures on my BDW machine, and this
problem is certainly BDW-specific. I just can't reproduce it on Haswell. So I
really think we should treat this bug as several smaller bugs.
For a better organization, we need to answer the following questions:
- What are the specific cases that fail on each platform?
- Why does it fail? Timeout? Testsuite claims FAIL? Test skipped?
- What are the output configurations used by each machine? For each machine
tested, please describe whether it has HDMI, eDP, DP, VGA, etc.
- Can we try to choose a specific failure from the list and bisect it? From
your comment above it seems the previous bisect result is bad, so we may need
to redo it.
After we get a concrete list of the problems, we need to re-evaluate the
priority of this bug, and decide whether we want to split it or not.</pre>
