Summary:                    Dahdi 2.1.0 causes HDLC Bad FCS (8) and Primary
D-Channel on span 2 down
Description: 
With one of our customers, with Dahdi 2.0.0, every day we see typically
between 50 and 80 messages of the type:

chan_dahdi.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span
2

These don't normally result in the span going down, so that's not so
serious.

We tried upgrading them to Dahdi 2.1.0, and got *1400* of these messages
over the course of the day.  The span went down 52 times over the course of
that day.

I reverted them back to 2.0.0 and things seem back to normal.
