asterisk users - Aug 2006 - sangoma a102: "Rx Error: 'Retry' exceeds maximum (64k): pci fatal error"

Hi,
after booting my server I get the following error:

Aug 17 16:40:57 localhost kernel: wanpipe1: Disable E1 CAS signalling mode!
Aug 17 16:40:57 localhost kernel: wanpipe2: Disable E1 CAS signalling mode!
Aug 17 16:40:57 localhost kernel: Registered tone zone 11 (Italy)
Aug 17 16:40:58 localhost kernel: wanpipe1:w1g1: Rx Error: 'Retry' 
exceeds maximum (64k): pci fatal error! (0x0007C03C)
Aug 17 16:40:58 localhost kernel: wanpipe1:w1g1: Rx Error: 'Retry' 
exceeds maximum (64k): pci fatal error! (0x0007C03C)

This happens with wanpipe-beta7-2.3.4 and wanpipe 2.3.3-3 and only after 
boot. If I make a wanrouter stop and then wanrouter start, I get no message.

Is there anybody who knows what this means?

TIA
