[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
I have a similar problem, Networkmanager 0.7 hangs or crashes my laptop (Dell xps m1330, Ubuntu Intrepid ibex 8.10) when I attempt to connect to a 3G internet account (Three Australia) via my USB connected Nokia E65 mobile phone. When I plug my device in, Networkmanager recognises it and runs the configuration wizard. Once the configuration is complete, the network is listed, but if I select it (to test the connection) the whole system locks/freezes/hangs and I have to hard reboot. I'd love to give you more information to isolate the problem - just tell me which commands/logfiles to run.

[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
After having done some research I'm now sure that this hang is due to the acx wireless driver and the fact that it does not support WPA. I can use NetworkManager if I blacklist this driver in /etc/modprobe.d/blacklist and use a wired connection instead. The worrying thing for Ubuntu is that this bug exists on the release candidate CD, the CD will not start at all if an acx111 based wireless card is present on the system. This would obviously preclude a number of users from installing and trying Intrepid. There are two ways to fix this issue, either blacklist the acx driver by default, or if the acx driver is present disable NetworkManager. In the long term the acx driver needs to add support for WPA, but I can't tell if the project is still being worked on. In the absence of any update to this driver NetworkManager should not enable WPA support by default for acx111 based cards. I would hope that resolving this issue would be a priority for the Ubuntu team as it would put off new users from converting to Linux and will leave current users unable to upgrade. I look forward to hearing your response to these comments. -- [intrepid] NetworkManager 0.7 hangs system https://bugs.launchpad.net/bugs/279287 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

I've managed to get a photograph of a stack trace of the problem, two parts of it are attached, unfortunately there was no way to write this information to a disk so I don't have the whole trace. Hopefully this will give you some information about the problem, could you please let me know if there's anything else I can try? ** Attachment added: "Picture 107.jpg" http://launchpadlibrarian.net/18585318/Picture%20107.jpg -- [intrepid] NetworkManager 0.7 hangs system https://bugs.launchpad.net/bugs/279287 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
[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
Hello again, attached is a photo of the output to the console after I issue the command to start network manager in no daemon mode, there is no output at all if I start it as a service. Alt+SysRq+t and Alt+SysRq+p gave no results. Unfortunately I can't do this on a tty as all are blank except for a blinking cursor, they are actually alive and I can log into them and echo text to a file to test, but I never get anything actually shown on the screen, even setupcon doesn't work. So, do you have any ideas what I can try next? Thanks, Steve. ** Attachment added: "nm_hang.jpg" http://launchpadlibrarian.net/18375740/nm_hang.jpg -- [intrepid] NetworkManager 0.7 hangs system https://bugs.launchpad.net/bugs/279287 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
[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
Thanks Stephen. Unfortunately, there is no trace of the crash in your log. I know you said that the machine completely dies, but I want you to try the following just on the offchance it produces something useful. Can you reproduce the crash from the console? If so, could you try the following: sudo su echo 8 > /proc/sys/kernel/printk exit .repeat steps to recreate the freeze here Does anything appear on the console? If so, please take a photograph incase it doesn't get written to disk, then try the following: Alt+SysRq+t - this will output all the tasks to the console if the machine is sufficiently alive. There will be too much info to fit on the screen if it works, and is only really useful if it gets written to disk. Alt+SysRq+p - this will give an indication of the current state of the CPU (if it works). Please photograph any results. If it works, it would be useful doing it 2 or 3 times. ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Chris Coulson (chrisccoulson) Status: Invalid => Incomplete -- [intrepid] NetworkManager 0.7 hangs system https://bugs.launchpad.net/bugs/279287 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
[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
The last boot that you see in kern.log is m boot into the recovery setup of Intrepid, the one before that is when the lock up happened. I'm willing to give any more information you may need and can build NetworkManager from source with any changes you may suggest if this will help to find the problem.

Chris, Sorry but it appears I spoke too soon. I've replaced the faulty memory with modules which pass memtest but I still get the problem. It's a complete system lock up, the SysRq process yields no results. The output of uname -a is: Linux steve-desktop 2.6.27-5-generic #1 SMP Fri Oct 3 00:36:38 UTC 2008 x86_64 GNU/Linux I'll also add the other files you requested. ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/18303724/dmesg.log -- [intrepid] NetworkManager 0.7 hangs system https://bugs.launchpad.net/bugs/279287 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

Hi, thanks for the quick responses, I've run the memtest and it looks like I've got a couple of sticky bits, so I think you can consider this closed.

[Bug 279287] Re: [intrepid] NetworkManager 0.7 hangs system
Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it without more information. Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team: 1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture. 2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report. 3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report. 4, After you have recreated the system hang and rebooted, please attach your /var/log/kern.log and /var/log/kern.log.0 files. It would be useful if you could annotate the files beforehand to indicate where you think the hang occurred (that's not absolutely necessary though). 5. Please run memtest, following the instructions here: https://help.ubuntu.com/community/MemoryTest 6. It would be useful to know how alive the system is. Could you try Alt+SysRq+R, E, I, S, U, B to see if the machine reboots? (you should pause for a few seconds between keypresses. See http://en.wikipedia.org/wiki/Magic_SysRq_key). If the machine is sufficiently alive, we may be able to get some useful debugging information from it.

system hangs in NM are most likely driver related.
