Gurvender.Bahia, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the 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-rc4 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: "snaps_06Aug13.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+attachment/3762556/+files/snaps_06Aug13.zip ** Tags added: latest-bios-2.80 ** Tags removed: needs-full-computer-model ** Summary changed: - Kernel Panic in 3.8.0, 3.8.1 & 3.8.2 when diconnecting from network manager, using ppp0 to connect to net + [Toshiba Satellite A80] Kernel 3.8.x Panic when disconnecting from network manager via ppp0 -- 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/1144322 Title: [Toshiba Satellite A80] Kernel 3.8.x Panic when disconnecting from network manager via ppp0 Status in “linux” package in Ubuntu: Incomplete Status in “linux” package in Arch Linux: New Status in Gentoo Linux: New Bug description: Using: "Ubuntu 12.04 (precise) 32-bit" Machine: Laptop / old Toshiba / Celeron processor Installing Kernel from: "http://kernel.ubuntu.com/~kernel-ppa/mainline/"; Apport disabled and uninstalled, so can't provide debug/log details (this to make the machine run a bit faster, have been doing so since 10.04). Have no problem with Kernel upto 3.7.10 (have been upgrading to Kernel 3.5/3.6/3.7/3.8, when ever new builds are available) But when using Kernel 3.8.0/3.8.1/3.8.2, get Kernel Panic & machine crashes & freezes, have to hard boot. Machine connects to net using "ppp0" (modem on phone), then if you disconnect the modem "ppp0" & try to reconnect, the Kernel Panics & crashes, or then if you disconnect by unchecking "Enable Networking" & then rechecking "Enable Networking", the Kernel Panics & crashes. First faced this problem with Kernel 3.8.0 so went back to using 3.7.9, then same story repeated with Kernel 3.8.1 & 3.8.2, currently using Kernel 3.7.10. Think there is some REGRESSION in Kernel 3.8 below details are provided using "HardInfo 0.5.1" : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322/+attachment/3761201/+files/hardinfo --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
