Huh?  Did you set ipv6.disable instead og ipv6.disable_ipv6?  Those are
very different, as documented in the module:


bjorn@miraculix:~$ modinfo ipv6
name:           ipv6
filename:       (builtin)
alias:          net-pf-10
license:        GPL
file:           net/ipv6/ipv6
description:    IPv6 protocol stack for Linux
author:         Cast of dozens
parm:           disable:Disable IPv6 module such that it is non-functional (int)
parm:           disable_ipv6:Disable IPv6 on all interfaces (int)
parm:           autoconf:Enable IPv6 address autoconfiguration on all interfaces (int)
