Public bug reported:
I have to say that since I upgraded to 14.10 I've been having tons of
problems with my wifi. Some of them seemed to be related to network-
manager while in some other cases not... I've noticed the following
entries in dmesg after suspend/resume which happend at the same time as
my wifi was having hard time to allow me viewing web pages or apt-get
commands being really really really slow.
