Since this is a regression, can you please bisect it? By the way, the bug description mentions "BYT" as the non-working platform, but the log file and bug title are for HSW.
(In reply to Paulo Zanoni from comment #1) > Since this is a regression, can you please bisect it? By the way, the bug > description mentions "BYT" as the non-working platform, but the log file and > bug title are for HSW. Sorry for that. I copy these words from other bugs and modified the content for this bug, sometimes I forgot to modify the platform. I had re-check these 2 cases on BYT and HSW from 2015-01-22 to 2015-02-12. These 2 cases had never been run on BYT. On HSW, it always fail except on 2015-02-11, subcase 2x-vblank-vs-dpms-suspend success that day, but when I tried to run this case with the kernel that day, it failed. So this bug is not a regression, and platform is only on HSW.

Tried running both 2x-vblank-vs-dpms-suspend and 2x-vblank-vs-dpms-suspend-interruptible on a HSW w/ latest nightly and can't reproduce. Could you confirm that this still happens on HSW?
Just FYI, the 2x cases are prone to fail unless the two pipes are running at precisely the same refresh rate. Otherwise they'll eventually drift apart causing the test to fail. Neither does the kernel attempt to minimize the phase difference between the pipes even if the refresh rates are identical. We should probably do that, especially for the "multiple MST streams make up one display" case. Otherwise that could lead to a visible tear between the "panels".
