[Asterisk-Users] Zaptel HDLC (NetHDLC) errors on modprobe, Linux 2.6 kernel

[Lenny Tropiano / asterisk.org Mailing list]

I have my Linux 2.6 kernel with the necessary HDLC config and also recompiled
zaptel accordingly.  On modprobe, I get:

Zaptel config /etc/zaptel.conf:
  span=1,1,0,esf,b8zs
  nethdlc=1-24
  loadzone = us
  defaultzone=us

The HDLC config does work, I am able to sethdlc and bring up the connection.... not sure
why we're getting those errors above, is there anything that can be done to make it cleanly
load?

Thanks.
