Kasper Dupont, 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 (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-v3.13-rc3 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. ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** 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/868498 Title: Kernel update broke graphics driver due to gcc segfault Status in “linux” package in Ubuntu: Incomplete Bug description: After upgrading from 2.6.32-33-generic to 2.6.32-34-generic X was no longer working on my system. During install an alert had appeared in the Gnome status bar indicating an install error for the psb-kernel- source driver for the graphics chip in this machine. The alert did not provide any information on where to find logs from the failing install, thus making further debugging hard. Moreover the button to report the bug directly from the alert was not functional. After a bit of searching I found out that I could run the driver build manually by running this command as root: dkms ^Cild -k 2.6.32-34-generic -m psb-kernel-source -v 4.42.0 This also failed, but at least pointed at the logfile in /var/lib/dkms /psb-kernel-source/4.42.0/build/make.log In this logfile I could see that the reason for the failure was that gcc was segfaulting during the build. The segfault would happen at different points during the build. The following workaround worked for me: 1. Add "kernel.randomize_va_space = 0" to /etc/sysctl.conf 2. Reboot 3. Uninstall linux-image-2.6.32-34-generic 4. Install linux-image-2.6.32-34-generic again 5. Reboot This is a regression as no such problems happened during earlier kernel upgrades. The kernel has been upgraded a few times already on this machine without problems. The last upgrade that worked without problems was to 2.6.32-33-generic, which worked flawless and would also have performed a build of this driver. I don't know which component is responsible for the gcc segfaults, so I am reporting this against my best guess.
