asterisk users - Jul 2010 - VPMADT032 Failed! Unable to ping the DSP (2)!

Running Asterisk 1.6.2.9, DAHDI 2.3.0.1, CentOS 5.5 (update to date as of a
week ago), I've installed a Digium AEX800P with 2 X400M FXO Modules and 1
VPMADT032 Module, hooked up to 5 analog lines.  I get the error message
referenced in the subject in my dmesg output everytime I load / reload DAHDI
using the command "system dahdi start/restart".  When I make an
outbound
call over these analog lines, I'm told in the CLI " WARNING[22601]:
chan_dahdi.c:2685 dahdi_enable_ec: Unable to enable echo cancellation on
channel 5 (No such device)", and there is noticeable echo on the line,
hearable by the caller inside the office, not by the recipient outside the
office.  When I make an inbound call, I get the same message, with echo
still heard by the person inside the office, and not outside.  I've run
fxotune -i 4 -e 5 also, and still receive the same output.

Below is my chan_dahdi.conf, my system.conf, my dmesg output while loading
dahdi, if you need anything else let me know:

*** chan_dahdi.conf ***

The last two lines of the dmesg output then repeat over and over again over
time in the dmesg output.

Any help you can offer would be much appreciated!

You should contact Digium technical support for assistance with this.
They can walk you through the troubleshooting process.

The most immediate thing you can do to limp along is enable sw echocan
by editing /etc/modprobe.d/dahdi and add "options wctdm24xxp
vpmsupport=0" and ensure you have software echocan configured in
/etc/dahdi/system.conf, which dahdi_genconf will do by default.

Cheers,
Shaun
