Debian Squeeze dahdi 2.4.1 dahdi_dynamic_ethmf

Hi All
I use redfone with Asterisk and dahdi in Squeeze box and I got an error
Unloading DAHDI hardware modules: ERROR: Module dahdi_dynamic_ethmf is in use
ERROR: Module dahdi_dynamic is in use by dahdi_dynamic_ethmf
ERROR: Module dahdi is in use by dahdi_dynamic

when /etc/init.d/dahdi stop called or the system reboot .
I looked in /etc/rc6.d and dahdi is invoking before netwotk stop.
I can’t make my mox in production and … I’m very blocked


Uncomment shutdown_dynamic # FIXME: needs test from someone with dynamic spans
in /etc/init.d/dahdi was my solution
