Description Ville Syrjala 2016-02-15 16:51:15 UTC
Seems to have been present since
Maybe that was when the check got added?

Doesn't seem to hit it every time.
Comment 1 Ville Syrjala 2016-02-22 15:04:11 UTC
Happens on BYT too since CI_DRM_1034 or so.
Comment 2 Matt Roper 2016-02-25 16:45:50 UTC
Seems to happen sporadically on kms_pipe_crc_basic@suspend-read-crc-pipe-c as well.
Comment 3 Tvrtko Ursulin 2016-03-04 10:01:21 UTC
Another sighting:

Comment 6 Joonas Lahtinen 2016-03-30 10:59:26 UTC
One more occurrance /archive/results/CI_IGT_test/Patchwork_1712/bsw-nuc-2/html/bsw-nuc-2@Patchwork_1712@1/igt@pm_rpm@basic-rte.html

Full message:

[drm:intel_runtime_suspend [i915]] *ERROR* Unclaimed access detected prior to suspending

Pretty safe to say this is BSW specific (not so much per test), so changing the title too.
Comment 7 Ville Syrjala 2016-04-12 17:55:14 UTC
Should be fixed now.
