            Bug ID: 101167
           Summary: [BAT][SKL] igt at kms_flip@basic-flip-vs-dpms produces a
                    dmesg-fail
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: martin.peres at free.fr

Starting from CI_DRM_2645, the test igt at kms_flip@basic-flip-vs-dpms sometimes
produces a dmesg-fail on fi-skl-6700hq because of the following assertion:

(kms_flip:3948) igt-kms-CRITICAL: Test assertion failure function
kmstest_set_connector_dpms, file igt_kms.c:1030:
(kms_flip:3948) igt-kms-CRITICAL: Failed assertion:
drmModeConnectorSetProperty(fd, connector->connector_id, dpms, mode) == 0
(kms_flip:3948) igt-kms-CRITICAL: Last errno: 22, Invalid argument

This may be related to having the following errors in the logs:
[  414.849575] [drm:intel_dp_start_link_train [i915]] *ERROR* failed to enable
link training
