Fixed in trunk in http://bazaar.launchpad.net/~apport-
hackers/apport/trunk/revision/2890

I tested it with /dev/nvram on amd64 (I just saw that this also exists
there) and it works now. If you want you can apply this simple fix
inline in /usr/lib/python3/dist-packages/apport/hookutils.py for
testing, but I'll upload a stable release update for this too.

Status in apport source package in Utopic:
  In Progress

Bug description:
  ---Problem Description---
  apport fails to collect nvram specific information
   
  ---uname output---
  3.16.0-10-generic
   
  Machine Type = POWER8 
    
  ---Steps to Reproduce---
   
  1) Install Ubuntu 14.10 in Power non-virtualized environment.
  2) Install apport package
  3) Run following command to verify if apport collects power specific information.

     apport-cli -f -p linux-generic --save=/home/sachin/linux.apport

  The command fails with following error :

  root@lep8d:/home/sachin# apport-cli -f -p linux-generic
  --save=/home/sachin/linux.apport

  Looking at the code we are doing a cat /dev/nvram to the apport output file which doesn't sounds right to me. I would think using the function add_tar() creating a tar file and copying the content as a ascii file at end of apport output file more appropriate.
  One dummy question remaining, how getting the tar file from the ascii output file if we need to ? ( that's also true to validate the content of the DeviceTree tar file).

  Would suggest following patch:
