Thx. Could you also try if reverting the patch from 6.16.y helps? Note, you might need to revert "drm/xe/guc: Set RCS/CCS yield policy" as well, which apparently depends on the patch that causes your problems.

Yes, reverting both dd1a415dcfd5 "drm/xe/guc: Set RCS/CCS yield policy" and 97207a4fed53 "drm/xe/guc: Enable extended CAT error reporting" from 6.16.y fixes the issue for me.
