I did a git pull up to 3.19-rc1 separately on the 3 boxes and used the 
.config from 3.18.0 as the base of make oldconfig.

When the build failed I did "make mrproper" and used the .config from 
one of the other boxes, then from the other, all 3 .config gave the same 
error.

Successfully rebooted one of the boxes.
