Package: network-manager Version: 0.9.4.0-1 Severity: normal Tags: ipv6 When using N-M in IPv6 automatic mode, it expects a DHCPv6 answer, and if it's missing the link will flag. The timeout can be rather long, in this case ~3.5 hours, but the laptop have been in standby portions of the time frame.

My home router do not send RA's with O(ther) or M(anaged) flags set so there isn't any DHCPv6 answer to wait for (unless it's trying to get a PD, which makes no sense for a host). pelle@apu:~$ rdisc6 -1 wlan0 Soliciting ff02::2 (ff02::2) on wlan0...

I've tried other IPv6 modes in N-M, for example "Automatic, addresses only" but with that one the IPv6 connectivity is really bad (maybe another bug should be posted...) and "test-ipv6.com" reports a broken system (2-3/10 if I recall correctly). With "automatic" I get a perfect 10/10. If I do turn off IPv6 (Ignore in N-M), I have a perfectly stable IPv4 link without any spurious link flaps. Note: The changed N-M.conf is just me setting on loglevel debug for IP6. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (600, 'testing'), (400, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages network-manager depends on: ii adduser 3.113+nmu1 ii dbus 1.4.18-1 ii dpkg 1.16.2 ii isc-dhcp-client 4.2.2.dfsg.1-4 ii libc6 2.13-27 ii libdbus-1-3 1.4.18-1 ii libdbus-glib-1-2 0.98-1 ii libgcrypt11 1.5.0-3 ii libglib2.0-0 2.30.2-6 ii libgnutls26 2.12.18-1 ii libgudev-1.0-0 175-3.1 ii libnl-3-200 3.2.7-2 ii libnl-genl-3-200 3.2.7-2 ii libnl-route-3-200 3.2.7-2 ii libnm-glib4 0.9.4.0-1 ii libnm-util2 0.9.4.0-1 ii libpolkit-gobject-1-0 0.104-2 ii libuuid1 2.20.1-4 ii lsb-base 3.2+Debian31 ii udev 175-3.1 ii wpasupplicant 0.7.3-6 Versions of packages network-manager recommends: ii crda 1.1.2-1 ii dnsmasq-base 2.60-2 ii iptables 1.4.12.2-1 ii modemmanager 0.5.2.0-1 ii policykit-1 0.104-2 ii ppp 2.4.5-5 Versions of packages network-manager suggests: ii avahi-autoipd 0.6.31-1 -- Configuration Files: /etc/NetworkManager/NetworkManager.conf changed [not included] -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
