Comment 1 Steve 2019-01-02 22:46:14 UTC

kernel 4.19.10-300.fc29.armv7hl per Bug 1661961, Comment 18.

Comment 2 Greg Kurz 2019-01-15 17:29:35 UTC

This is fixed upstream by the following commit:

commit 9619c8619c37b9aea98100bcc15c51a5642e877e
Author: Greg Kurz <groug>
Date:   Thu Aug 30 12:01:59 2018 +0200

    Kill bogus TYPE_BLOB marker type

https://github.com/dgibson/dtc/commit/9619c8619c37b9aea98100bcc15c51a5642e877e

It got merged quite early after 1.4.7 so I believe it should be easy to
apply on top of the official tarball.

Cheers,
