Yuvraaj Kelkar, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. 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-v3.11-rc2 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 If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-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. Thank you for your understanding. ** Attachment removed: "uname-a.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1205210/+attachment/3749576/+files/uname-a.log ** Attachment removed: "version.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1205210/+attachment/3749577/+files/version.log ** Attachment removed: "lspci-vvnn.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1205210/+attachment/3749558/+files/lspci-vvnn.log ** Tags added: latest-bios-a17 needs-upstream-testing regression- potential ** 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/1205210 Title: BUG: unable to handle kernel NULL pointer dereference at IP: [<ffffffff81044a99>] __ticket_spin_lock+0x9/0x30 Status in “linux” package in Ubuntu: Incomplete Bug description: System details: Dell Inspiron E1505. 2GB RAM, 200 GB SSD. I have a Logitech Dinovo Edge keyboard which I am able to pair, connect and then use. Every once in a while I get this kernel oops and it drops to text. Its possible to get back to X with Ctrl+Alt+f1 and the C-A-f7. However, the bt keyboard then no longer works. Rebooting the machine results in a hang. The only recourse so far seems to be to hard reboot. --- ApportVersion: 2.9.2-0ubuntu8.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: uv 2336 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=e26f02d0-0462-4873-88bb-9a582b4cfbb8 InstallationDate: Installed on 2013-04-27 (89 days ago) InstallationMedia: Kubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Dell Inc.
