The problem is that the ipv6 module is loaded too late, namely only _after_ the procps init script tries to set the ipv6 parameters. See http://bugs.debian.org/507788 for the gory details. The workaround for that is to load the ipv6 module before the procps init script runs, e.g. by adding it to /etc/modules: # echo ipv6 >> /etc/modules Note that Squeeze kernels have ipv6 built in, so in Debian 6.0 most people will not be affected by this problem anymore.
