Before you can uninstall the Diva System Release software, you need to unload the Diva driver modules.
The Diva driver modules can be unloaded simply by executing: /usr/lib/opendiva/divas/Stop
If you wish to stop and unload the Diva drivers modules manually, proceed as described below:
Login as "root" (or use su -).
If you have started any tools that access the CAPI or Diva TTY interfaces, stop these tools to release the interfaces.
If you have modified /etc/inittab or /etc/ttys to start getty/mgetty/ppp on one of the Diva TTY interfaces, remove these entries from these files and execute kill -HUP 1.
Check that the Divastty, capi and divacapi modules are not busy (call lsmod to check it).
Execute rmmod capi && rmmod divacapi && rmmod kernelcapi to unload the CAPI drivers.
Execute rmmod Divatty to unload the Diva TTY drivers.
Execute rmmod diva_idi && rmmod divas && rmmod divadidd to stop and unload the XDI drivers.
