asterisk users - Feb 2006 - Zap channels Deactivated with Bristuff-0.3.x after upgrade from 0.2.0

Hello,
I have about 10 Asterisk PBX in production with Bristuff-0.2.0-RC8q  
(asterisk 1.0.10) and I want to use Bristuff-0.3 now for the new PBX  
I am going to set up.
With Bristuff-0.2.0-RC8q the ISDN lines are working fine, but the new  
version of Asterisk add some nice features.
All these PBX are in France with France Telecom lines.
When I use the new version after about an hour with Euronumeris lines  
and almost instantly with Euronum?ris+ line, TE lines goes  
Deactivated in /proc/zaptel/:

Span 1: ZTHFC1 "HFC-S PCI A ISDN card 0 [TE] layer 1 DEACTIVATED  
(F7)" AMI/CCS

            1 ZTHFC1/0/1 Clear (In use)
            2 ZTHFC1/0/2 Clear (In use)
            3 ZTHFC1/0/3 HDLCFCS (In use)

I have tested almost all the possible settings for /etc/zaptel.conf  
and /etc/asterisk/zapata.conf
There is no IRQ sharing for the HFC-PCI cards.

When cards are deactivated, I can receive calls, but not make call.
The cards in NT mode seems to work fine (connected to an Alcatel PBX).
All the cards are 1 port HFC-PCI cards. I also have an 8 ports card  
from Junghanns.net but this card is on a production server and it's  
hard to use it for test.

Almost all the PBX are on Centos 3.4 with kernel  2.4.21.

Does someone have this problem to?

I can post the configuration files if it can help.

Best regards
