Package: laptop-mode-tools Version: 1.72-3 Severity: normal Tags: ipv6
By default, laptop-mode is configured to control eth0. However, this seems to cause eth0 to become active prematurely before NetworkManager can take control of it. Excerpt from journalctl: [...] Mar 29 00:24:53 ritchie laptop-mode[7040]: enabled, not active Mar 29 00:24:53 ritchie kernel: r8169 0000:03:00.0 eth0: Link is Up - 1Gbps/Full - flow control rx/tx Mar 29 00:24:53 ritchie kernel: IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [...] Mar 29 00:24:58 ritchie avahi-daemon[597]: Joining mDNS multicast group on interface eth0.IPv6 with address [...]. Mar 29 00:24:58 ritchie avahi-daemon[597]: New relevant interface eth0.IPv6 for mDNS. Mar 29 00:24:58 ritchie avahi-daemon[597]: Network interface enumeration completed. Mar 29 00:24:58 ritchie avahi-daemon[597]: Registering new address record for [...] on eth0.*. [...] After that, the device appears managed to NetworkManager, such that it does not do any IPv4 configuration for it and does not set up /etc/resolv.conf, either. As a workaround, I need to either reconnect eth0 from the NetworkManager GUI after each start-up or remove eth0 from the devices controlled by laptop-mode. The role of avahi-daemon in this scenario is not entirely clear to me. In newer configurations, this bug will likely not show up due to the new naming scheme of networking interfaces, but then the primary network device will not be controlled by laptop-mode, either. -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-updates'), (500, 'proposed-updates'), (500, 'testing'), (500, 'stable'), (400, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages laptop-mode-tools depends on: ii lsb-base 10.2019031300 ii psmisc 23.2-1 ii util-linux 2.33.1-0.1 Versions of packages laptop-mode-tools recommends: ii ethtool 1:4.19-1 ii hdparm 9.58+ds-1 ii net-tools 1.60+git20180626.aebd88e-1 ii python3-pyqt5 5.11.3+dfsg-1+b3 ii rfkill 2.33.1-0.1 ii sdparm 1.10-1 ii udev 241-1 ii wireless-tools 30~pre9-13 Versions of packages laptop-mode-tools suggests: ii acpid 1:2.0.31-1 -- Configuration Files: /etc/laptop-mode/conf.d/usb-autosuspend.conf changed [not included] -- no debconf information
