Building/loading dahdi from asterisk

[Alex]

Hi,

I'm really stuck with getting asterisk started. I've built and install
the dahdi asterisk modules, but they don't load automatically on boot.

The asterisk-dahdi package includes /etc/rc.d/init.d/dahdi which runs
"/bin/systemctl start dahdi.service" but it fails to load the modules.

My question is, how do I troubleshoot this? How do I get more
information to find out why it isn't automatically load the modules?

If I just run "modprobe dahdi" manually, it loads the modules.

I've looked through the logs, and it just says "Started LSB: DAHDI
kernel modules." without any further information.

Any ideas greatly appreciated.
Thanks,
Alex
