[Etienne URBAH <eurbah@xxxxxxx>]

I have upgraded all my machines from 'utopic' (with linux 3.16) to 'vivid' (with linux 3.19) where this bug is fixed.
So, I do not PERSONALLY need a backport.

But this bug still exists for 'utopic', and perhaps even LTS 'trusty'.
So, it is possible that this bug needs a backport to 'utopic' and LTS 'trusty'.

For 'utopic' and LTS 'trusty', this bug may be closed only AFTER :
-  a backport corrects the problem (then the status would be " Fix Released") or
-  the Ubuntu release has reached its end of life (then the status would be "Won't Fix').

Anyway, this bug is perfectly valid, and its status must NOT be set to
"Invalid".
