Hi, I RANDOMLY get the same error. I posted all the apport-collect out put above. There are several related bugs (maybe identical) and threads listed here (some of them):

After a fresh install, I used to get this shutdown crash. For a couple of days it went away. But then it again came back. I did install some packages in between (totally unrelated to wireless: acroread etc.) 2- Usually (not always) when I shutdown/restart the machine on battery, everything seems to be OK. No kernel panic, no iwlagn error. nothing. 3- It seems that when I turn off the wireless and then shutdown/restart, everything is OK. 4- Some users have observed that when splash is removed from the menu.lst, the problem doesn't happen. I have also observed that. Although, I didn't permanently remove the splash - I just did it a couple of times using grub editor during boot up, and in all those instances, the shutdown process went smoothly. I don't know if this was just random or not. 5- I couldn't find a version of kernel traceback in /var/log/kern.log or /var/log/kern.log.0 (it seems to be missing from there). However, during shutdown, when I press CTRL+ALT+F7, there is a kernel panic. The last messages before the kernel panic is this (I wrote down from the monitor): [ 371.328580] iwlagn: Error: Response NULL in 'REPLY_ADD_STA' [ 371.344681] general protection fault: 0000 [#1] SMP [ 371.344752] last sysfs file: /sys/devices/pci0000:00/0000:00:1c.2/0000:04:00.0/rfkill/rfkill0/state [ 371.344831] Dumping ftrace buffer: The picture of the rest of the traceback is attached. After the traceback, the following messages appear: * Killing all remaining processes... [fail] * Deconfiguring network interfaces... [OK] * Unmounting temporary filesystems... [OK] * Deactivating swap... [OK] * Unmounting local filesystem.... [OK] * Will now halt And then hangs indefinitely. I can either press and keep power button to turn it off, or I can press CTRL+ALT+DEL to restart the system. Looking at the kernel panic, it seems that something is wrong with iwlagn. 6- A suggested work-around can be found in this forum: http://ubuntuforums.org/showpost.php?p=7149271&postcount=22 Some users have reported that this work around fixes their problem. However, this might be just random as well. ** Attachment added: "Photos of the Kernel Panic" http://launchpadlibrarian.net/27160906/KernelPanicPhoto.tgz -- Jaunty - Wireless issue causes laptop shutdown to hang indefinitely https://bugs.launchpad.net/bugs/365733 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
