Execute command sudo -s echo disk > /sys/power/state 2. Wait 60 seconds 3. Resume with keyboard Actual result: -------------- Suspend to disk and resume do not work Expected result: ----------------- Suspend to disk and resume work
Assigned to me to provide logs and details of investigation
Can you try to capture logs either with netconsole or a serial console? Also is it confirmed that i915 is the culprit here? Does the failure to resume also occur without i915 loaded or compiled in?
Same note I wrote on the S3 bug applies here: """ Please try downgrading your DMC firmware to version 1.05 to see if that makes a difference; my team has seen some suspend/resume failures that only happen with the 1.06 DMC. Also, as Jesse mentioned, ensure that i915 is the culprit by trying to suspend/resume without it in the picture. Some of our early silicon has suspend/resume issues that are unrelated to software stack. """
Assigned to Humberto: Please try without i915 and also with DMC 1.05
Hi : After 5 attemps looks like that the BXT-P resume without any issues with DMC 1.05 and with the kernels (i915_no_loaded / drm-intel-testing) (attached dmesg.log) attached dmesg.log This was the configuration used during the test : Bios : 119.10 KSC : 1.0 OS : Ubuntu 14.04.03 LTS x86_64 Graphic stack versions : ----------------------------------------- cairo version: 1.15.2 / commit : db8a7f1 drm version : libdrm-2.4.66 / commit : b38a4b2 intel-driver : 1.6.2 / commit: 683edee libva version : libva-1.6.2 / commit : 304bc13 mesa version : mesa-11.0.8 / commit : 261daab xf86-video-intel version : 2.99.917 / commit : baec802 xserver version :xorg-server-1.18.0 / commit :7921764 kernel drm-intel-testing: ------------------------------------------ commit 91587c722c28c4116dedbfbf08aa874377bc76f8 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Dec 4 17:35:54 2015 +0100 drm-intel-nightly: 2015y-12m-04d-16h-35m-07s UTC integration manifest kernel version : 4.4.0-rc3 git url : git://anongit.freedesktop.org/drm-intel git branch : drm-intel-testing git describe : drm-intel-next-2015-11-20-rebased-13721-g91587c7 Kernel without i915 loaded: --------------------------------------------- commit b54e0f487f15213e85ca80c9ae9b953eb617cb42 Author: Jani Nikula <jani.nikula@intel.com> Date: Thu Jan 7 11:52:35 2016 +0200 drm-intel-nightly: 2016y-01m-07d-09h-52m-06s UTC integration manifest
