asterisk users - Jan 2014 - B410P BRI card testing with patgen / pattest

Hello,

I have a card here at the office that I'm trying to validate with some
tests. For now I've followed the  instructions available here:
http://kb.digium.com/articles/Configuration/Back-to-Back-Pattern-Test-for-BRI-Adapters
.

I get this kind of output:

[..]
(.Error 44119): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44120): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44121): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44122): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44123): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44124): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44125): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44126): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44127): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44128): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44129): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44130): Unexpected result, 255 != 0, 1 bytes since last error.
[...]

This goes on continuously, like a massive flood, not a small burst in the
beginning like the KB article mentions.

Would this be the kind of output that matches a problem card or something
may be wrong in my setup? I'm using DAHDI 2.8.0.1.

Any input appreciated, thanks!

Regards,
Rodrigo
