Marked as confirmed because I am unable to user apport-collect, as commented above. I tried in all the way I can, but launchpad refuses to allow the data upload. 
I used apport_cli --save apport_report.txt  linux and attached the resulting file. 


** Changed in: linux (Ubuntu)
       Status: Incomplete => Confirmed

** Attachment added: "result of apport_cli --save apport_report.txt  linux"

Title:
  Trusty Thar, kernel 3.13: automatic load of wacom.ko driver cause a
  "hard" kernel panic

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have just upgraded to 14.04 from 13.10.

  I have a wacom cth-480  touch+pen tablet, which was not recognized on
  13.10 (kernel 3.11). With the stock kernel from 14.04, I have an
  immediate kernel panic as soon as I plug in the tablet to the laptop.

  The system is a asus 1005PE (32 bit install), Xubuntu, up-to date:
  Linux asus-romano 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:08:14
  UTC 2014 i686 i686 i686 GNU/Linux

  The really strange thing is that if I manually load the driver with
  `sudo modprobe wacom` *before* pluggin the tablet in, then the tablet
  is recognized and works ok:

  A screenshot of the kernel panic is added. I can reproduce it at will.
