DAHDI Make

If you have upgraded your kernel when doing a system update with

apt-get update
apt-get upgrade

you may need to recompile DHADI. Login as root and

cd /usr/src
ls -l
# see the dahdi dir similar to dahdi-linux-complete-xxxxxx
# cd into that directory
cd dahdi-linux-complete-xxxxxxxx
make
# if no errors
make install

Then reboot
