matteo sisti sette, 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 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 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. 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-v3.11-rc5 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 ** Tags added: bios-outdated-306 ** Changed in: linux (Ubuntu) Status: Confirmed => 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/903321 Title: Hibernation fails irreversibly ("not enough swap space") Status in “linux” package in Ubuntu: Incomplete Bug description: Most of the times (but not always) when I hibernate, the error message appears: "MP: not enough swap space" and the hibernation hangs forever. Or it seems to complete (meaning the power goes off) but then when I turn on the computer it fresh boots instead of resuming. If the swap space is really insufficient, and if this is really the cause of the issue, there are at least a couple of bugs: 1. Hibernation should be atomic: either it can complete succesfully or it should be reversed completely, or not be initiated at all. It must be guaranteed that the system never ever finds itself in an intermediate state where hibernation cannot complete but cannot be reversed. All conditions that are needed to complete succesfully should be checked before the hibernation is initiated. Checking whether there is enough swap space is particularly easy, I guess. 2. I din't choose the amount of swap space when I installed ubuntu, nor did I change it afterwards, nor did I ever increase the amount of RAM after installation. The size of the swap partition is the one that was proposed by the installer by default. The installer should propose by default a swap partition size that is guaranteed to allow the system to function properly, including hibernation. AND if the user chooses a size for the swap partition that _may_ be insufficient a warning should be issued before allowing the installation to begin.
