Tvrtko Ursulin, can you indicate on which platforms it is happening (ALL?), the kernel version/commit id and a dmesg when the error occurs?

Comment 2 Tvrtko Ursulin 2016-02-26 14:22:22 UTC

/archive/results/CI_IGT_test/igt@kms_force_connector_basic@force-load-detect.html

ILK, IVB, SNB, HSW by the look of if.

    drm/i915: Do not return unknown status when load detection is tested.
    
    This fixes the IGT test, which interprets unknown status as failed to
    acquire load detect pipe.
