we hit WARN_ONCE in:
"
/* If mode timing undefined, just return as no-op:
* Happens during initial modesetting of a crtc.
*/
if (mode->crtc_clock == 0) {
DRM_DEBUG("crtc %u: Noop due to uninitialized mode.\n", pipe);
WARN_ON_ONCE(drm_drv_uses_atomic_modeset(dev));
return false;
}
"
Strange that the "Noop due to uninitialized mode" is not in dmesg.
