-               Due to some issues there is one more change you have to make before attempting your 
-               build.
+               Before attempting to build the modified kernel there is one more set of changes you 
+               need to make in the <filename>meta-kernel-dev</filename> layer.
+               Because all the kernel <filename>.bbappend</filename> files are parsed during the 
+               build process regardless of whether you are using them or not, you should either 
+               comment out the <filename>COMPATIBLE_MACHINE</filename> statements in all 
+               <filename>.bbappend</filename> files, or you should simply remove all the files 
+               except the one your are using for the build (i.e. <filename>linux-yocto_2.6.37.bbappend</filename>
+               in this example).
