I have a TDM400P that is working under Elastix 1.5.2-2.2. After a reboot, when I look at the CLI there is no dahdi loaded (not even any dahdi function visible in the help). In hardware, I see the card, but the channel is 'not in use' I need to click detect hardware and then do an amportal restart to have it working. I haven't see anything special in the dmsg log. where should I look?
