This is also visible on GDG. Not sure why GDG hits it every time, and these things apparently only in the shard runs. Some kind of fb leak somewhere... *** Bug 102938 has been marked as a duplicate of this bug. *** Also on, igt@drv_module_reload@basic-no-display https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3118/shard-hsw1/igt@drv_module_reload@basic-no-display.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3119/shard-hsw2/igt@drv_module_reload@basic-no-display.html https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3119/shard-snb5/igt@drv_module_reload@basic-no-display.html Also, KBL-shards: https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3119/shard-kbl2/igt@drv_module_reload@basic-no-display.html *** Bug 102576 has been marked as a duplicate of this bug. *** Yes this just indicates an fb leak in any of the previously run tests. module-reload is just the canary. So step 1: take note of all the previous tests run in the same shard, step 2: figure out which one it actually is. Yes this is one of the more painful ones.
