["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

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.

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" :
