The specified patch is already included.  The system was running the 
latest kernel from Robert Nelson's repo.  Any suggestions?  I'll try 
removing some of the patches to see if it fixes this behavior.  I have a 
feeling I know which one is doing it.

Thanks.

/home/bbuild/comp/kernel/patches/adc/0017-IIO-ADC-ti_adc-Fix-1st-sample-read.patch: 
applied

Just in case, I built and installed the kernel and the same behavior 
persisted.

                    <br>
                    It seems I've stumbled upon a problem while
                    developing a full featured Ruby gem for the
                    Beaglebone.<br>
                    <br>
                    It seems a patch included in the beaglebone kernel
                    causes some issues while reading analog inputs.
                    &nbsp;Apparently the samples get backlogged by the number
                    of adc pins in use. &nbsp;I'm not sure which patch
                    exactly as there are a number that affect adc
                    buffering and I'm not currently setup for kernel
                    building, however the below output should detail the
