I don´t actually remember, but I obviously missed something :-(
With similar problem reports in Nokia/MeeGo, that´ s what I added last week:

From: Rémi Denis-Courmont <remi.denis-courmont@nokia.com>
Subject: [PATCH] Phonet: device notifier only runs on initial namespace

This should really fix the OOPS when doing:

  unshare(CLONE_NEWNET);
  exit(0);

while the phonet module is loaded.
