Thanks for your report.  The first failing test is:

--8<---------------cut here---------------start------------->8---
test-name: channel-news, one entry
location: /home/ep/src/guix/tests/channels.scm:266
source:
+ (test-assert
+   "channel-news, one entry"

[...]

+              (lset= equal?
+                     (map channel-news-entry-tag
+                          (channel-news-for-commit channel commit5 commit1))
+                     '(#f "tag-for-first-news-entry")))))))

I wonder if this could be caused by settings in ~/.gitconfig.  Could you
try to move it out of the way and run the test?  With:

  rm ~/.gitconfig{,.bak}
  make check TESTS=tests/channels.scm

The second failure is:

--8<---------------cut here---------------start------------->8---
test-name: reverse bag DAG
location: /home/ep/src/guix/tests/graph.scm:194
source:
+ (test-assert
+   "reverse bag DAG"

+     (((dune bap ocaml-base)
+       (values
+         (specification->package "dune")
+         (specification->package "bap")
+         (specification->package "ocaml-base")))

[...]

actual-error:
+ (quit 1)
result: FAIL
--8<---------------cut here---------------end--------------->8---

It’s due to recent changes in the OCaml packages.  I’ll push a fix
shortly.

Thanks!

Ludo’.
