Roland Lohner, 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, but the one all the way at the bottom) 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. ** 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/1071699 Title: [Dell Lattitude E6420] Boot fails with kernel 3.5.0 Status in “linux” package in Ubuntu: Incomplete Bug description: Kubuntu 12.10 64bit fails booting on my Dell Lattitude E6420 notebook. Previous version 12.04.1 worked fine. After upgrade to 12.10 system no more boots. Kubuntu 12.10 64bit DVD does not boot, either, with same symptoms. When using the old kernel (3.2.0) and initramfs, system boots properly. Using the new kernel (3.5.0) splash screen shows, dots are moving in the logo. Then the logo stops moving and then system freezes, I am not able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.2.0 kernel.
