G400e not detected on dahdi restart

Hi,

We are using a centos 6 system, kernel 2.6.32-358.23.2.el6.x86_64
Dahdi 2.6.1 and Asterisk 1.8.24 compiled from source
Chan_extra 2.0.7

when we restart the box, the card is detected and shows up on /proc/interrupts
however, if we stop the dahdi service and restart it, the card no longer shows up on /proc/interrupts and and dahdi cant see the card!
now I expect that opvxg4xx should unload when I stop dahdi, but it should re-load when I restart dahdi!
opvxg4xx doesnt seem to reload when the dahdi service is restarted!


For example:

[root@pbx ~]# dahdi_cfg -vvv
DAHDI Tools Version - 2.6.1

DAHDI Version: 2.6.1
Echo Canceller(s): HWEC, MG2
Configuration
======================

SPAN 1: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)
SPAN 2: CCS/ AMI Build-out: 0 db (CSU)/0-133 feet (DSX-1)

Channel map:

Channel 01: Clear channel (Default) (Echo Canceler: mg2) (Slaves: 01)
Channel 02: Hardware assisted D-channel (Default) (Echo Canceler: none) (Slaves: 02)
Channel 03: Clear channel (Default) (Echo Canceler: mg2) (Slaves: 03)
Channel 04: Hardware assisted D-channel (Default) (Echo Canceler: none) (Slaves: 04)

4 channels to configure.

Setting echocan for channel 1 to mg2
Setting echocan for channel 2 to none
Setting echocan for channel 3 to mg2
Setting echocan for channel 4 to none

You should add opvxg4xx to /etc/dahdi/modules, then the driver module for G400E will be loaded when restart dahdi service.

Ok, well that needs to be documented somewhere!

The installation script did not add it in, and it isnt mentioned anywhere in the manual or the wiki!
