Hi Greg,

root@beaglebone:~# rmmod pru_rproc
rmmod: ERROR: Module pru_rproc is in use

or 

root@beaglebone:~# modprobe -r pru_rproc
modprobe: FATAL: Module pru_rproc is in use.

I am using kernel 4.4.9-ti-r25  Debian 8.6

I did not flash a new image - this is straight out of the box.  Do you know 
what the mechanism is that blocks the module remove in the OS?   

Neil
