            Bug ID: 98981
           Summary: [IVB] igt/gem_exec_suspend/basic-s3 hangs when used
                    with intel-ci/fast-feedback.testlist
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: IGT
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: dorota.czaplejewicz at collabora.co.uk

The test igt/gem_exec_suspend/basic-s3 does not wake up from suspend when
invoked as part of the testlis tintel-ci/fast-feedback.testlist

Manual wake up is needed, afterwards test reports pass.

I am in the process of finding the minimal test case.

So far, the smallest test set that triggers this:
sudo IGT_TEST_ROOT=`pwd`/intel-gpu-tools/tests ./piglit/piglit run igt -o
results -l verbose -s --test-list
intel-gpu-tools/tests/intel-ci/fast-feedback.testlist -t gem_exec

While specifying tests separately, the hangup does not occur:



Log of the complete run with a manual wakeup:
Time    0:04:10.425812
Stdout  

IGT-Version: 1.17-g901c2bb (x86_64) (Linux: 4.9.0-rc7-CI-CI_DRM_1849+ x86_64)
rtcwake: wakeup from "mem" using /dev/rtc0 at Sat Dec  3 11:19:08 2016
Subtest basic-S3: SUCCESS (18.487s)
