Yeah, that's a heck of a lot of bisecting and builds. However, since 3.13 is the trusty kernel, I figured I'd try the latest of that, and it works there as well - so upstream has patched it on that maintenance branch as well. I'm going to reverse bisect that instead (should be shorter). ** Tags added: kernel-fixed-upstream-3.13.11.11 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1404242 Title: Radeon crash on 14.04 LTS stops Xorg from starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1404242] Re: Radeon crash on 14.04 LTS stops Xorg from starting
Okay, digging in to this, I grabbed the kernel repos from upstream and added the kernel.ubuntu.com remote, and in looking at those and getting my bearings, I see that there is an Ubuntu-3.13.0-44.73, which is one version greater than what I'm running, and I find that it is in trust- proposed. So, I grabbed those packages, installed them, and this fixes the problem. Of a note on workflow - this ticket was opened on 19 Dec. That kernel was built 16 Dec. Having me test that kernel would have been a more rapid resolution then messing about with upstream kernels, etc. To summarize: - this is already fixed - the kernel in trusty-proposed getting promoted to the main repository will fix the issue -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1404242 Title: Radeon crash on 14.04 LTS stops Xorg from starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Finally got around to testing this (apologies, holidays). This is fixed in v3.19-rc2-vivid, which I think further lends credence to my speculation that this bug is the same as #1397553, only for Trusty. ** Tags added: kernel-fixed-upstream kernel-fixed-upstream-3.19-rc2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1404242 Title: Radeon crash on 14.04 LTS stops Xorg from starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Matthew Caron, the next step is to fully reverse commit bisect from kernel 3.13 to 3.19-rc2 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.

Matthew Caron, thank you for reporting this and helping make Ubuntu better. As per http://www.gigabyte.com/products/product-page.aspx?pid=2763#bios an update to your computer's buggy and outdated BIOS is available (F7). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-f7 ** Changed in: linux (Ubuntu) Importance: Undecided = Low ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1404242 Title: Radeon crash on 14.04 LTS stops Xorg from starting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1404242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry about that - the board is so old, it never occurred to me that there may be a BIOS update (indeed, IIRC, I build the system in June of 2008, so I didn't see the July update). Anyway, updated BIOS to F7. No change in behavior. It is as originally described.

[Bug 1404242] Re: Radeon crash on 14.04 LTS stops Xorg from starting
Matthew Caron, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test 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 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 exactly shown as: kernel-fixed-upstream-3.19-rc1 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. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.
