Intel Atom (MATOM) ------ info: https://cateee.net/lkddb/web-lkddb/M686.html I know that, in the past, we have been careful to not require certain processor features on i686, such as SSE [0]. I would appreciate some guidance, both about this kernel configuration option, and what we have historically considered to be the "minimum requirements" for i686 hardware. I will put that information the manual so that it doesn't get lost. Leo [0] https://lists.gnu.org/archive/html/guix-devel/2016-07/msg01534.html
