I'm facing this problem or something very simmilar in Ubuntu 11.04. The first symptom is nm-applet not able to associate with a Wifi network. Logs shows that network manager manage to associate with the access point, eventually the interface will get an IP address but as nm- applet or network manager fails to understand it, it will disconnect and restart a full association cycle.
At this moment the only solution is to logout, shutdown gdm, stop dbus, remove /var/run/dbus/pid restart dbus restart gdm and login. I tried to restart gdm and not stopping dbus and I got a dialog box saying that gdm/X11 is in failsafe mode. I faced already this problem a couple of time after some days of activity, for instance right now my laptop is up since ~6.5 days. I'm doing compilations on it (mostly wireshark and samba) a couple of time a day. Problem don't seems to occurs while compiling and even not just after compilation. ** Attachment added: "Strace of dbus after it has gone "crazy" and while starting GDM" https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/656134/+attachment/2161943/+files/strace_dbus -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/656134 Title: dbus periodically becomes unresponsive and a reboot is required to regain system functionality To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/656134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
