Can you pls boot with drm.debug=0xe added to your kernel cmdline and attach the complete dmesg (just so we know about your hw)?

Still have problems viewing the video, but hotplug detection is being run once a second. Could be the culprit.

Could you help to update the issue? if you need any information, please let me know.Thanks~

That's just the normal garbage that occurs when the output is still scanning out from the GTT as we rewrite it for GEM. Should be fixed (once again) with the preliminary fast boot support.
