The CI Bug Log issue associated to this bug has been updated. ### New filters associated * TGL: igt@kms_flip@2x-flip-vs-suspend-interruptible - dmesg-fail - Failed assertion: (do_page_flip(o, new_fb_id, !(o->flags & (1 << 16)))) == 0 - https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_7266/re-tgl-u/igt@kms_flip@2x-flip-vs-suspend-interruptible.html
This look like test error on first look. There's call to drmModePageFlip() which return "16, Device or resource busy" which would mean it's second call to drmModePageFlip() before page flip event happened.
