Comment 1 Marta Löfstedt 2018-01-03 07:13:43 UTC 
This issue is caused by IGT regression:

commit 98c64b33a7935fb334c73bb0fc9e76f416b81069
Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
Date:   Thu Dec 7 09:21:36 2017 +0100

    lib/igt_kms: Drop all stale events on first commit.
    
    I've been trying to make kms_cursor_legacy work when subtests fail.
    Other subtests will start failing too because of expired events or
    stale pipe crc. The latter can be resolved in the test, but the former
    could affect other tests

    [mlankhorst: Change return status to int, so callers can see how many events are swallowed.]

Comment 3 Marta Löfstedt 2018-01-03 11:34:12 UTC 
I will monitor and close once we have a CI_DRM run with positive results.
Comment 4 Marta Löfstedt 2018-01-03 13:53:38 UTC 
the fix is integrated in IGT_4109 the test pass. I will close and archive this bug.
