Hi! > And if you can indeed reliably reproduce this a bisect could be really useful. And we have a winner here :-) Ok, it was not as painfull as I feared. It does not revert cleanly, but doing it by hand was not that bad. Best regards, Pavel a51435a3137ad8ae75c288c39bd2d8b2696bae8f is the first bad commit commit a51435a3137ad8ae75c288c39bd2d8b2696bae8f Author: Naresh Kumar Kachhi <naresh.kumar.kachhi@xxxxxxxxx> Date: Wed Mar 12 16:39:40 2014 +0530 drm/i915: disable rings before HW status page setup Rings should be idle before issuing sync_flush (in intel_ring_setup_status_page).
