*** Bug 96975 has been marked as a duplicate of this bug. *** Humberto, can you apply https://patchwork.freedesktop.org/series/10104/ and confirm that issue is fixed? You have to run that test in a loop since it is sporadic. Not yet. Perhaps with the third patch, https://patchwork.freedesktop.org/series/10124/ but these races are both highly unlikely and not specific to that one bdw-u. Something is not quite right here. https://patchwork.freedesktop.org/series/10124/ appears more promising. Hi : after apply the patch from : https://patchwork.freedesktop.org/series/10124/ and try for 10 times this test it passed with the following configuration on BDW-U Hardware information ============================================ Platform : BDW Motherboard model : 80E5 Motherboard type : Lenovo G50-80 Notebook Motherboard manufacturer : LENOVO CPU family : Core i5 CPU information : Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz GPU Card : Intel Corporation Broadwell-U Integrated Graphics (rev 09) (prog-if 00 [VGA controller]) Memory ram : 6 GB Maximum memory ram allowed : 16 GB Component : drm tag : libdrm-2.4.69-25-g1af780c commit : 1af780c Component : cairo tag : 1.15.2-49-g56ad58a commit : 56ad58a Component : intel-gpu-tools tag : intel-gpu-tools-1.15-135-g250f047 commit : 250f047 kernel used ================================================ commit 9953d9959d06f69b36255f398ce6158f1e5bb5a8 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Thu Jul 21 07:57:39 2016 +0100 drm/i915: Check for a stuck waiter before a missed interrupt As the interrupt wakeup counter only increments when we have a waiter, before testing to see if that counter is unchanged we have to first check that we do expect it to change (i.e. we have a waiter).

Chris could you tell us when the patch in on nightly branch please ? Thanks The first two are, which more or less indicate that it is not a false positive (or at least from that particular race).
