Elastix 2.0 + A400P problem

Hi,
I have the problem when I installed the Elastix 2.0. The A400P has not been detected when startup. The following is the error messages. Please kindly advise

DAHDI Tools Version - 2.3.0
Notice: Configuration file is /etc/dahdi/system.conf
line 0: Unable to open master device '/dev/dahdi/ctl'

1 error(s) detected

I cannot find the answer can solve the problem..Thanks a lot.

Hi,
(1) Checking the A400P hardware by command: lspci –vvvvv

If you can see a Tiger Jet chip base device, It shows the A400P has been identified by the system.
else, please plug out the A400P and plug it in other PCI slot.
(2) run the following command
amportal stop
service dahdi stop
modprobe dahdi
modprobe wctdm
dahdi_genconf
dahdi_cfg -vvvvvvvvv

Thanks a lotxin, I will try it first.

Sys can find the A400P and change the PCI slot, but when I type modprobe dahdi. It has the error message

FATAL: Module dahdi not found

Please advise

Change the other PC and reinstall the Elastix, it works, Thanks
