It should be CONFIGURE_MAXIMUM_DRIVERS. I don't know if 5 is the right number but you need 1+ driver slots empty beyond the static drivers configured to account for the dynamically installed one. https://git.rtems.org/rtems/tree/cpukit/sapi/include/confdefs.h?h=4.10#n856 should be the section of code you are tripping.
