Created attachment 119942 [details] 4.4-rc1-nightly_screen-off-when-resuming-from-S4_kern.log Hardware Platform: SKY LAKE Y A0 QUAL CPU : Intel(R) Core(TM) M5-6Y54 @ 1.10GHz 4MB (family: 6, model: 78 stepping: 3) MCP : SKL-Y D0 QDF : QJ9W CPU : SKL D0 Chipset PCH: Sunrise Point LP C0 CRB : SKY LAKE Y LPDDR3 RVP3 CRB FAB2 Reworks : All Mandatories + FBS02 & FBS03, O-06 Software Linux : Ubuntu 14.04 64 bits BIOS : SKLSE2R1.R00.B104.B01.1511110114 ME FW : 11.0.0.1191 Ksc (EC FW): 1.20 Kernel 4.4.0-rc1 nighlty 2e0db75 from git://anongit.freedesktop.org/drm-intel commit 2e0db751f53791a654eaeb829efd2b4125249dfc Author: Imre Deak <imre.deak@intel.com> Date: Wed Nov 18 21:49:07 2015 +0200 drm-intel-nightly: 2015y-11m-18d-19h-48m-48s UTC integration manifest Mesa 11.0.5 from http://cgit.freedesktop.org/mesa/mesa/ xf86-video-intel - 2.99.917 from http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/ Libdrm - 2.4.65 from http://cgit.freedesktop.org/mesa/drm/ Libva - 1.6.1 from http://cgit.freedesktop.org/libva/ vaapi intel-driver - 1.6.1 from http://cgit.freedesktop.org/vaapi/intel-driver Cairo - 1.14.2 from http://cgit.freedesktop.org/cairo Xorg Xserver - 1.17.2 from http://cgit.freedesktop.org/xorg/xserver Steps: ------ 1. Boot with kernel boot command line: i915.disable_power_well=1 2. Execute commands: sudo -s echo disk > /sys/power/state 3. Wait 60 seconds 4. Resume with keyboard Actual result: --------------- 4. DUT resumes (DUT is responding via ssh) but screen stays off Expected result: ---------------- 4. DUT resumes with screen on
Workaround: Screen is back after a suspend to mem
Looks like we don't do a full modeset after resume from S4 as we should. Perhaps the fastboot issue that got recently: commit 7383123647566a813692bb37a1389c767ed89158 Author: Jani Nikula <jani.nikula@intel.com> Date: Thu Nov 19 10:26:30 2015 +0200 Revert "drm/i915: skip modeset if compatible for everyone." Could you try with latest nightly again?
Bug scrub: Assigned to me. I will test again with last nightly and check results of basic tests.
