Thank you for taking the time Bruce. Yes, that is essentially what I was 
trying to do. Two SRC_URI += in a .inc, one listing the patches, the other 
just listing a cfg file. The only difference is that as it was a mainline 
kernel recipe I included it from a .bb, not a .bbappend. The .bb inherits 
'kernel'.

I originally had the additional patches in a subdirectory to separate them 
out, but to eliminate file paths as a cause, I moved them in with the main 
patches with no luck. I'll revert the changes and try again so I can 
provide some specific log results.
