Public bug reported: On my system after updating today, I see network manager bring up my wifi link and then immediately start reconnecting.
In my dmesg, I see many sequences of messages like [ 2027.559748] NetworkManager[7265]: segfault at 0 ip 00007f03d9939f7d sp 00007fff1f62cbb0 error 4 in libc-2.15.so[7f03d9833000+1b3000] [ 2027.561881] init: network-manager main process (7265) killed by SEGV signal [ 2027.561942] init: network-manager main process ended, respawning my /var/log/apport.log shows ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: called for pid 6970, signal 11, core limit 0 ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: executable: /usr/sbin/NetworkManager (command line "Network Manager") ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: is_closing_session(): no DBUS_SESSION_BUS_ADDRESS in environment ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: this executable already crashed 2 times, ignoring (I lost some reports because of course apport fails to upload while the network is down) Not sure what's going on, but I do note that there is a new network- manager version as of today.
