Gurvender.Bahia, one would need to be using a Ubuntu repository kernel
to run the apport-collect. As per
https://launchpad.net/ubuntu/+source/linux , for Precise this would be
3.2.0-51.77.

Title:
  Kernel Panic in 3.8.0, 3.8.1 & 3.8.2 when diconnecting from network
  manager,  using ppp0 to connect to net

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" :
