Hello! Linux-libre 4.9.0 triggers this problem on i686 (quoting <https://hydra.gnu.org/build/1713833/nixlog/21/raw>):
--8<---------------cut here---------------start------------->8--- loading kernel modules... [ 6.085552] libahci: disagrees about version of symbol mcount [ 6.085978] libahci: Unknown symbol mcount (err -22) ./gnu/build/linux-modules.scm:195:6: In procedure load-linux-module*: ./gnu/build/linux-modules.scm:195:6: In procedure load-linux-module: Invalid argument --8<---------------cut here---------------end--------------->8--- With 4.8.14, things went well: <https://hydra.gnu.org/build/1689159/log/raw>. To reproduce, run, for instance: ./pre-inst-env guix system vm gnu/system/install.scm -s i686-linux <https://patchwork.kernel.org/patch/9380911/> suggests this might be a 4.9 bug. Mark, any ideas? Did anyone get 4.9 running on i686? If not, I suggest reverting the 4.8.14 → 4.9 upgrade for the release. Ludo’.
