Closing the linux (Ubuntu) task as what appears the most sane solution
wouldn't be use an older linux kernel that supports tomoyo-tools 2.4
(which isn't going to happen) but backport a newer version of tomoyo-
tools into Precise.

** Description changed:

  # lsb_release -rd
  Description:	Ubuntu 12.04.1 LTS
  Release:	12.04
  
  PROBLEM: The latest 12.04LTS kernel expects TOMOYO 2.5 policies. However
  the version of the TOMOYO tools in 12.04LTS is TOMOYO 2.4.
  
  SYMPTOM: Kernel panic on policy loading attempt.
  
  REPRODUCE: Install linux-image-3.2.0-36-generic (3.2.0-36.57). Install
  tomoyo-tools (2.4.0-20111025-3). Initialize TOMOYO policy. Reboot with
  kernel option "security=tomoyo" and observe panic.
+ 
+ WORKAROUND: Copy tomoyo-tools-2.5 package from Ubuntu 12.10's repository
+ into Ubuntu 12.04's repository.

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