James Hunt, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: needs-upstream-testing This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: needs-upstream-testing If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Please let us know your results. Thank you for your understanding. ** This bug is no longer a duplicate of bug 751689 ThinkPads overheat due to slow fans when on 'auto' ** Package changed: gnome-session (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/954391 Title: "something" is performing a controlled system shutdown Status in “linux” package in Ubuntu: Incomplete Bug description: I'm not entirely sure where or why this is happening, but I have seen on ~5 occasions now my system spontaneously switch off. Initially, I thought it might be an init/kernel issue, but today I saw the problem occur twice and crucially, I also got to see the console and there was no kernel panic - the system was shutting itself down cleanly as if the user had typed, "sudo shutdown -h now" or selected "shutdown" on the Unity panel. I'm seeing this on a fully updated Precise system. I'm wondering what higher-level parts of the system might possibly be invoking "/usr/lib /indicator-session/gtk-logout-helper --shutdown" or the D-Bus org.freedesktop.ConsoleKit.Manager.Stop() method?
