asterisk users - Apr 2010 - B400P and A1200P changes card order

Hi,


I've run into a veird problem. I'm using a B400P BRI and an A1200P card 
with dahdi (2.2.1) driver. The dahdi_scan shows the each moduls and 
spans, everything seems fine. With dahdi_genconf I made the config, set 
up the channels in chan_dahdi.conf, but after reboot, the two card 
changes the order, (originaly the B400P is the first (closer to the 
processor) and A1200P is the second), when I check with dahdi_scan, it 
shows the channels are not in the original order. I set the Card ID 
Switch to 0 on B400P but it does not solve the problem. I tried these 
cards with another motherboard, the situation is the same so it's not 
chipset specific.

Please let me know if there is any solution. Thank you for your help in 
advance.

Best regards,
Peter

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,
