Bug ID: 99130 Summary: [IVB] CONFIG_PROVE_LOCKING=y causes igt/gem_exec/basic-wait-all (and possibly others) to fail Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: IGT Assignee: dri-devel@lists.freedesktop.org Reporter: dorota.czaplejewicz@collabora.co.uk
Created attachment 128524 --> https://bugs.freedesktop.org/attachment.cgi?id=128524&action=edit basic-wait-all log
Kernels built with the default CI config (e.g. https://intel-gfx-ci.01.org/CI/CI_DRM_1968/kernel.config.bz2 ) will trigger failures in the test igt/gem_exec/basic-wait-all The failures will rarely appear immediately; for faithful reproduction, running the test several times consecutively is needed (at least 4 times). Afterwards, the failures will be constant.
Changing CONFIG_PROVE_LOCKING from "=y" to "=n" will stop the failures.
