[Marc Branchaud <1495696@xxxxxxxxxxxxxxxxxx>]

I suffered from these messages after upgrading to Kubuntu 16.04.

After changing my hard drive, then my entire PC, then upgrading the
kernel to 4.5.2 and also my nVidia drivers to 364.19, the messages went
away.

However, I STILL saw intermittent lockups.  These finally went away
after I turned off KDE's file indexing (baloo-file-indexer).  I suspect
that my original NMI problems could have also stemmed from that.

I've latched onto bug #1548051 for the file-indexing problem.
