Commen= t # 18 on bug 98333<= /a> from Alex Deucher 
If the modes are only in the CEA extension block then this is =
a core drm issue.
 The core EDID parser does not handles all of the CEA 4K modes yet.  Patches
were proposed by several people, but I don't think any of them have gone
upstream yet due to various objections and bikeshedding.  See:
