DAHDI_SPANCONFIG failed on span 1: No such device or address (6)

DAHDI_SPANCONFIG failed on span 1: No such device or address (6)

Trying to upgrade Asterisk and DAHDI drivers and came across this error. I could not get DAHDI to reload.

These are the steps I took to have DAHDI load the modules properly.

Remove DAHDI modules
modprobe -r wctc4xxp wctdm24xxp wcte12xp xpp dahdi_transcode wcb4xxp
modprobe -r wctdm wcfxo wctdm24xxp wcte11xp wct1xxp wcte12xp

modprobe -r dahdi_voicebus wct4xxp wctdm24xxp dahdi
Move these folders to a temporary location just in case:
mv /etc/modprobe.d/dahdi* /tmp/

mv /etc/dahdi /tmp/

Download DAHDI drivers and recompile:
cd /usr/src
wget http://downloads.asterisk.org/pub/telephony/dahdi-linux-complete/dahdi-linux-complete-current.tar.gz

tar -zxvf dahdi-linux-complete-current.tar.gz

cd dahdi-linux-complete…VERSION

make; make install; make config

/etc/init.d/dahdi restart
