** Description changed:

- PBR routing is broken using some kernel versions.
- Problem occurs on server and desktop versions.
+ Kernel breaks PBR routing on several versions.
+ Problem occurs on server and desktop.
+ 
+ Example using linux-image-3.13.0-70
  
  lsb_release:
  Ubutu 14.04.3 LTS
  Release 14.04
  
  Expected:
  To have the normal rule table when using 'ip rule show'
   0:      from all lookup local
   32766:  from all lookup main
   32767:  from all lookup default
  
  Instead:
  The 'ip rule show' command is messed up showing lots of repeated rules for local/main/default (did not count them - simply too much)
  It seems like it stucks within a loop adding/displaying and adding/displaying... but the system is not blocked.
  A sec prob in my case as it is making policy based routing useless if you need to grep whether your rule exists already.
  
  Workaraound, go back to/remain on either of these series:
  3.13.0-68
  3.16.0.51
+ 
+ PBR NOT working on:
+ 3.13.0-69
+ 3.13.0-70
+ 3.16.0-52
+ 3.16.0-53
