Peter,

I'm not familiar with the A1200P, but I suspect the A1200P not blacklisted in /etc/modprobe.d.  Therefore when you reboot, it's driver is loaded by udev before the rest of the DAHDI drivers are loaded.

Try adding the driver for the A1200P to /etc/modprobe.d/dahdi.blacklist to make sure that the drivers are loaded by any configuration scripts in /etc/init.d in a consistent order.

Cheers,
