Does this happen for all types of output (DP, VGA, HDMI, eDP) or just a few? For external outputs, does it also happen with different monitor models with the same connector type? Note: In dmesg we have tons of DP link train failures, so I guess this is about DP. Created attachment 85539 [details]
dmesg: remove i915 have the same issue
I append the dmesg without i915 loaded here.

DP && HDMI pipe: These two kind of pipes even can't light up when machine boot up, but reachable. I have tried many different monitor, all of them are black screen. Our machine doesn't support DP and HDMI. I have asked my partner who owner this machine. Today I find our machine can't resume from S3/S4, it hangs there. Turn back to test the kernel which I reported with, it also doesn't work now. Older kernels are bad too. I find a NOTOURBUG which is reported by Kobeqin, the result is the same with it: Bug #67731 - [Baytrail-M] system can't resume from S3/S4 .

Sorry, our machine is unstable, S3/S4 are able to resume today. So this bug will not be blocked now. Further testing is on the way, if there's any issue, I will comment in the first time. Can you give this patch a try? http://lists.freedesktop.org/archives/intel-gfx/2013-September/033970.html (In reply to comment #7) > Can you give this patch a try? > > http://lists.freedesktop.org/archives/intel-gfx/2013-September/033970.html Test this patch on latest -next-queued, it works well. The monitor can display correctly when machine resume from S3. commit 40e9cf649a88abea96d5756aa6f86e89cfabde6e Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Thu Oct 3 11:35:46 2013 -0700 drm/i915/vlv: reset DPIO on load and resume v2 Note for the backlight we may still have an issue if the panel is on the second pipe.
