Tang Dahong, 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 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 XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ 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 ** Tags removed: bios-outdated-2.21 ** Tags added: latest-bios-2.21 ** Changed in: linux (Ubuntu) Status: Confirmed =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/1446724 Title: server is stable under older kernel (3.2.0-29.46), but crashes under newer kernels Status in linux package in Ubuntu: Incomplete Bug description: My PC is stable running Ubuntu Server 12.04.5 LTS using the old kernel 3.2.0-29.46. But it crashes whenever I tried to update the kernel to 3.2.0-65.99 or higher (including 14.04.2 LTS). So somewhere between 3.2.0-29.46 and 3.2.0-65.99, changes to the kernel caused my PC to crash (note: I have not tried kernels older than 3.2.0-65.99, so I don't know the exact version that started to cause the crash). I think this is likely a hardware compatibility issue since I could not find any system logs regarding the crashes. My PC is very old (Compaq Evo D510 SFF/07E4h, BIOS 68602 v2.14 08/15/2002), so I am not sure if this bug is worth troubleshooting. In the meantime, I am happy with the performance of my PC running 3.2.0-29.46. But if anyone is interested in troubleshooting this bug, please let me know. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.13.0-32-generic.
