from system.conf:
-------------------
# dchan::
#   The DAHDI driver performs HDLC encoding and decoding on the
#   bundle and also performs incoming and outgoing FCS insertion
#   and verification.  'fcshdlc' is an alias for this.
# hardhdlc::
#   The hardware driver performs HDLC encoding and decoding on the
#   bundle and also performs incoming and outgoing FCS insertion
#   and verification.  Is subject to limitations and support of underlying
#   hardware.
--------------------

If you are getting that error then you probably have old hardware that 
does not support 'hardhdlc', use 'dchan' instead.
