Hello Rolf
I originally filed this bug in 2014. Sadly, nothing was ever done to

Title:
Maximum CPU
I don't know if this occurred in a release prior to Trusty so I
downloaded 12.04.3 LTS (Precise Pangolin) - the distro linked to in your
post - and ran it from a USB stick. The short answer is that the
problem also exists in Precise. Slightly longer answer - the CPU is
recognised/named correctly

This bug affects me too on an Acer Aspire 5720 laptop. Running sudo
restart network-manager works but it's a PITA having to do this every
time the laptop wakes up from Suspend.
This problem did not exist on 13.04. It only appeared after upgrading
to 13.10.
