I am currently testing v6.6 with the culprit commit reverted. I need to test for at least a full week (ending 11-23) before I can assume it fixes the problem. After that I can try the latest v6.7-rc as you suggested. I have updated the bug description at <https://gitlab.freedesktop.org/drm/nouveau/-/issues/180>. Thanks again, Owen -- Owen T.
