I have a server running 4.2 upgraded from 4.0 & 4.1. I had problems ( services not starting with the server & 100% cpu usage) with the 3.16.0-52-generic kernel and I purged it
and it installed 3.16.0-53-generic and I had the same issue so I purged again -53 and used apt-get to install 3.16.0-51-generic.
Since then it boots but all the hardware has gone, no video drivers and no network drivers. Lo is loading fine.
Is this broken now or can it be fixed?!
