        <pre>Nothing obvious in the logs. The one change is that we now set the infoframe
for the LSPCON chip.

Can you test with latest drm-tip branch to make sure we haven't fixed this in
the meantime?
git://anongit.freedesktop.org/drm-tip drm-tip


To rule out the infoframe we could try something like this:
diff --git a/drivers/gpu/drm/i915/intel_lspcon.c
b/drivers/gpu/drm/i915/intel_lspcon.c
index 8d202b13e24f..1eac926c0821 100644
--- a/drivers/gpu/drm/i915/intel_lspcon.c
+++ b/drivers/gpu/drm/i915/intel_lspcon.c
@@ -473,6 +473,8 @@ void lspcon_set_infoframes(struct intel_encoder *encoder,
        const struct drm_display_mode *adjusted_mode =
                &crtc_state->base.adjusted_mode;

+       return;
+
        if (!lspcon->active) {
                DRM_ERROR("Writing infoframes while LSPCON disabled ?\n");
                return;</pre>
