grege89, 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 images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please just make a comment to this. Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. 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. For example: kernel-fixed-upstream-v3.12 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-v1.15 regression-potential ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1010981 Title: Computer does not power off when attempting to shut down by any route. Status in “linux” package in Ubuntu: Incomplete Bug description: Computer does not shut down, but instead merely freezes at the graphical splash screen while remaining powered on, with monitor, fans, and all other hardware still running. I've attempted the following, all with no success: - Issuing halt, poweroff, halt -P, shutdown -h/-H/-P, and every other conceivable variation thereof from a terminal. Have also attempted these commands from a tty after killing X. - Graphical shutdown from unity panel. Have also tried this at login screen. - Have attempted to disable various services and kernel modules that have been implicated in other bug reports complaining of similar issues (namely, laptop-mode, acpi-support, proprietary fglrx driver, networking, and misc. others). - Various suggestions from Ubuntu forums (editing /etc/default/halt, updating grub with various different arguments to GRUB_CMDLINE_LINUX_DEFAULT, disabling network-manager service prior to attempting shut down, and others). This shut down malfunction happens invariably and with total predictability. Oddly, rebooting does initially appear to work, but when computer powers back on, the OS fails to load and instead hangs at a blank, purple screen (without the typical Ubuntu logo). Other relevant info: - Computer is an Acer Aspire 5560-7402 laptop. - Ubuntu is the sole OS, installed recently with default/automatic partitioning settings, using whole disk. - uname -srvmpio output: Linux 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux (please note that the problem began immediately after installation, i.e., before upgrade from 3.2.0-23-generic kernel). - lsb_release -rd output: Description: Ubuntu 12.04 LTS Release: 12.04 --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
