Summary:                    Kernel oops from NULL pointer dereference in
ioctl_echocancel
Description: 
I set up the MG2 echo canceller module for use with my FXO device. I was
attempting to test echo using the Echo application. After dialing the
extension for Echo the line goes dead and DAHDI becomes unusable. Below is
the dmesg output.

Running on Fedora 9 using SVN r4593 from /dahdi/linux/trunk.

system.conf:
loadzone=us
defaultzone=us
echocanceler=MG2,3
fxsks=2
fxoks=3
