Christopher, according the Ubuntu to Mainline kernel version mapping (http://people.canonical.com/~kernel/info/kernel-version-map.html), Ubuntu kernel 4.2.0-12.14 is based on Mainline kernel 4.2.1, but the error messages didn't appear while booting this Mainline kernel. Actually, all these Mainline kernel versions boot without the errors described in the bug report: 4.3-rc3, 4.3-rc1, 4.2.2, 4.2.1, 4.2, 4.2-rc8. Am I missing something? Maybe I didn't test the right kernels. Ubuntu Kernel 4.1.0-3.3 is installed and boots without errors. Should I test more kernels? -- 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/1501431 Title: Various i915 Intel display driver crashes reported on syslog Status in linux package in Ubuntu: Incomplete Bug description: Computer: Dell Latitude E5440.

Eric Carvalho, the next step is to fully reverse commit bisect from kernel 4.2 to 4.3-rc3 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

[Kernel-packages] [Bug 1501431] Re: Various i915 Intel display driver crashes reported on syslog
Eric Carvalho, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com /~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-a12 ** 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/1501431 Title: Various i915 Intel display driver crashes reported on syslog Status in linux package in Ubuntu: Incomplete Bug description: Computer: Dell Latitude E5440.
