The CI Bug Log issue associated to this bug has been updated. ### New filters associated * KBL: igt@kms_chamelium@hdmi-hpd-storm - Fail - Failed assertion: igt_hpd_storm_detected(data->drm_fd) - https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_202/fi-kbl-7500u/igt@kms_chamelium@hdmi-hpd-storm.html - https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_202/fi-kbl-7567u/igt@kms_chamelium@hdmi-hpd-storm.html
Only affects two KBL machines. Hit every few days. This test always fails on KBL. It always passes on other platforms. User impact: a bad cable can make a screen unusable.
