Ernie, I can confirm that 12.10 with original network-manager 0.9.6.0 has this problem and it appears during shutdown.
I do not play with unchecking of networking, it is always enabled. The patch mentioned in the comments fixes the issue for me. Another option is to install to 12.10 the following packages for Raring: libnl-3-200_3.2.16-0ubuntu1_amd64.deb libnl-genl-3-200_3.2.16-0ubuntu1_amd64.deb libnl-route-3-200_3.2.16-0ubuntu1_amd64.deb libnm-glib4_0.9.8.0-0ubuntu2_amd64.deb libnm-util2_0.9.8.0-0ubuntu2_amd64.deb network-manager_0.9.8.0-0ubuntu2_amd64.deb I have tested i686 and x86_64, with updated network-manager both systems cleanly unmount /. If you see the problem, please, provide the list of running processes and files open for writing when root filesystem is about to be remounted for readonly. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1124803 Title: NetworkManager doesn't respond to SIGTERM in daemon mode Status in NetworkManager: Fix Released Status in “network-manager” package in Ubuntu: Fix Released Status in “network-manager” package in Gentoo Linux: New Bug description: NetworkManager does not respond to SIGTERM when started in daemon mode, as upstart does by default. This also happens when running NetworkManager manually from the command line as long as the --no- daemon option is not used. This was reported upstream and was fixed by commit 64342a313ef497fca8a4fb7567900d4a1460065f It appears that this bug forces upstart to SIGKILL NetworkManager during shutdown, which, amoung other things, means that n-m doesn't deconfigure network interfaces as intended. This bug, along with bug 1124789 (in wpasupplicant), means that no attempt is made to disconnect from a wifi network during shutdown. This in turn triggers a bug in my BIOS which causes this system to hardlock in the middle of BIOS post when I reboot while still connected to a wifi network: http://thread.gmane.org/gmane.linux.kernel.wireless.general/102862 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: network-manager 0.9.6.0-0ubuntu7 ProcVersionSignature: Ubuntu 3.5.0-24.37-generic 3.5.7.4 Uname: Linux 3.5.0-24-generic x86_64 ApportVersion: 2.6.1-0ubuntu10 Architecture: amd64 Date: Wed Feb 13 22:32:52 2013 IpRoute: default via 10.179.201.1 dev eth0 proto static 10.179.201.0/24 dev eth0 proto kernel scope link src 10.179.201.80 metric 1 10.179.201.0/24 dev wlan0 proto kernel scope link src 10.179.201.105 metric 9 169.254.0.0/16 dev eth0 scope link metric 1000 MarkForUpload: True NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no SourcePackage: network-manager UpgradeStatus: Upgraded to quantal on 2012-10-20 (116 days ago) WpaSupplicantLog: mtime.conffile..etc.NetworkManager.NetworkManager.conf: 2012-03-21T22:57:56 nmcli-dev: DEVICE TYPE STATE DBUS-PATH wlan0 802-11-wireless connected /org/freedesktop/NetworkManager/Devices/1 eth0 802-3-ethernet connected /org/freedesktop/NetworkManager/Devices/0 nmcli-nm: RUNNING VERSION STATE NET-ENABLED WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running 0.9.6.0 connected enabled enabled enabled enabled enabled To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/1124803/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
