asterisk users - Aug 2006 - wanpipe1:w1g1: Rx Error: 'Retry' exceeds maximum (64k): pci fatal error! (0x0007C03C)

Hi,
I'm trying to install Asterisk 1.2.9.1 on a Debian Sarge distro with a 
Sangoma A102 using zaptel 1.2.6 and libpri 1.2.3.
Asterisk seems to work correctly but when I reboot the server I get the 
following error inside /var/log/messages:

localhost kernel: wanpipe1:w1g1: Rx Error: 'Retry' exceeds maximum 
(64k): pci fatal error! (0x0007C03C)

What does it mean exactly?

Notice that I haven't connected any PRI line to the card.

Is there a way to know if the card is working correctly?

TIA

Giorgio Incantalupo
