3) Networking going ok, no network-manager call trace
4) System slowing down a lot (file manager, anything), networking not
working (even if wifi seems connected from the top bar); I had to do not
a clean reboot because just clicking on "restart" was taking a lot of
time to shut down
I'm attaching the complete kernel log
