This could be caused by recent dtschema change, which was also recently fixed. The LKP report had dtschema git version and as you can check it points exactly to the version changing reserved nodes (which introduced issues). Not to the latest one which fixes the issue. If issue is reproduced with 840a01d but not with later, then obviously everything is fine. Best regards, Krzysztof
