I have tried to use my old 3.19.0 kernel that did not have the problem 
but now it will not boot.  The boot screen is left with

Loading Linux linux...
Loading initial ramdisk...

No logs etc.. I am guessing that some grub or ram disk change is giving 
me the problem.  I have just upgraded to Ubuntu 16.04 and do not want to 
downgrade so I am a bit stuck at the moment and doubt that I can do this 
test.
