It looks like your development box is having problems with
interrupts from the card. Once you run dahdi_cfg for the span  you
should be getting 10000 interrupts/sec and above I can see you only
got 28.

I've seen this recently with some risers which was the reason for
commit 10380 "wct4xxp: Fail startup if not generating interrupts."

Do your development boxes work with an older version of DAHDI? Just
not 2.3.0.1?  Also, why not upgrade to 2.5.0.2 or the trunk of the
2.6 branch?

Cheers,
Shaun
