We have linux-libre-4.4 (LTS) in Guix, but our 1.0.1 installer images are based on linux-libre-5.1. It might be worth using another machine to build a Guix installer image that uses linux-libre-4.4, and trying that. Here's how: Section 3.9 (Building the Installation Image) describes how to build an installer image, but instead of passing "gnu/system/install.scm", pass the name of a modified version of that file, with (kernel linux-libre-4.4) added as an additional field to 'installation-os'.
