Thanks for posting the problem and a possible soultion. To help with debugging you could do the following:
A good testcase is a step by step instruction to reproduce your bug starting with driver unloaded and NetworkManager stopped. Kill NetworkManager sudo killall NetworkManager To unload your driver modprobe -r DRIVER . Then load the driver and start NetworkManager: sudo NetworkManager Capture Log In order to understand whats going on and track down issues, its good to have a full log. To do so, capture the complete test case and submit the whole file (don't cut out what you think is important). Please add markers in the log file so the bug triager can easily see what actions the user takes at what point of time (this isn't essential, but helps a lot). To capture the syslog, do: tail -n0 -f /var/log/syslog > /tmp/syslog and to stop capturing do Ctrl-C (you will have to type your other commands in an other window or tab) Adding markers is just like adding new lines with an editor that show the triager what happened at what point of time. Example marker: Sep 6 08:12:30 ... [ clicked on wireless network 'ubuntu'] Sep 6 08:12:31 ... ... Debugging Crashes To install debug symbols, add the following line to your /etc/apt/sources.list deb http://ddebs.ubuntu.com/~ubuntu-archive/ddebs/ gutsy main universe Then install the appropriate dbgsym packages: sudo apt-get update sudo apt-get install network-manager-dbgsym libnm-util0-dbgsym libnm-glib0-dbgsym libglib2.0-0-dbgsym Then restart NetworkManager: sudo /etc/dbus-1/event.d/25NetworkManager restart Attach the debugger to the pid of NetworkManager sudo gdb /usr/bin/NetworkManager $(pidof NetworkManager) ... (gdb) continue Once it crashes get a backtrace (gdb) bt ... (gdb) bt full ... (gdb) thread apply all bt full ... and attach the backtrace above together with your /var/log/syslog to the bug. Driver Logs When a bug appears to be driver related or you are asked by a bug triager to submit a driver enabled log, you need to enable driver logging right before you start to capture your testcase. How to do that depends on the driver you use and whether it has been with compiled with debug support. -- iwl3945 fails to connect to MR814 access point https://bugs.launchpad.net/bugs/203705 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
