[asterisk-users] DAHDI has broken by pbx :-(

I bit the bullet last night and upgraded from Asterisk 1.4.42 with
Zaptel 1.4.12.1 to Asterisk 1.8.7.1 and DAHDI 2.5.0.2 (libpri is 1.4.12
for both configs).
Everything went reasonably well except for calls to and from an ISDN PBX
on span 2..... which now just won't work :-(
There's obviously something different in the Zap/DAHDI settings that I
need to tweak but I've read through the config samples and not been able
to find anything.
Can anyone help?
For the record, no hardware was changed and everythings been working
fine for yonks with my 1.4.42 based setup.
FWIW, I also tried DAHDI 2.6.0-rc1 and libpri-1.4.11.5 but neither made
any difference.
The ISDN PBX (a Network Alchemy Argent) is connected to port 1 on my
Digium Wildcard TE205P. Port 0 on the card is connected to a BT ISDN30
line which is working fine.
I copied my settings from /etc/zaptel.conf to /etc/dahdi/system.conf.

Asterisk/DADHI sees both spans but whenever I try dialing anthing on
span 2 I get the following in /var/log/asterisk/messages
>[Nov 10 13:28:07] NOTICE[30988] chan_dahdi.c: PRI got event: HDLC Abort (6) on D-channel of span 2
>[Nov 10 13:28:08] WARNING[30988] sig_pri.c: Span 2: No D-channels available! Using Primary channel as D-channel anyway!
and on the console I get:
>-- Executing [*42 at from-sip:1] NoOp("SIP/112-00000003", "DAHDI Dial Test") in new stack
>-- Executing [*42 at from-sip:2] Dial("SIP/112-00000003", "DAHDI/g2/18") in new stack

>== Everyone is busy/congested at this time (1:0/0/1)
>-- Auto fallthrough, channel 'SIP/112-00000003' status is 'CHANUNAVAIL'
and then all the Channels on Span 2 get restarted.
DAHDI is also seeing CRC errors that goes up by one every time the
D-Channel on span 2 goes up/down.

Which shows the call terminating with Cause 18 (no user responding). huh?
Can anyone suggest how I can get this fixed?
TIA
