After rereading the bridge_ignore_without_connections.patch, i agree with you about a problem with connection matching.
IMHO the problem are not the lines you referred to, they are only a inherited error and aren't logged with a network-manager without the patch. But: <debug> [1390763529.436635] [nm-manager.c:1898] add_device(): MATT: should inhibit: true in conjunction with nm-manager.c:1947 if ( !manager_sleeping (self) && !nm_device_spec_match_list (device, unmanaged_specs) && !inhibit_managed) { is resulting in a not called nm_device_set_managed. Obviously this is the cause. The unanswered question is why nm-manager.c:1895 nm_device_connection_match_config returns NULL. The config i'm using with network-manager (0.9.8.8-0ubuntu1) and network-manager (0.9.8.8-0ubuntu1) minus bridge_ignore_without_connections.patch is exactly the same and attached. ** Attachment added: "/etc/NetworkManager/NetworkManager.conf" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1273201/+attachment/3963295/+files/NetworkManager.conf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273201 Title: bridge_ignore_without_connections.patch breaks NM created bridge at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1273201/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
