[Asterisk-bsd] IRQ misses

[freebsd at wcubed.net]

Hello all,

I'm getting ready to turn up a new * box with a T100P.  I'm running
6-STABLE and was able to build and install zaptel, libpri and asterisk
with no issues whatsoever.  However, when I run ztcfg I get thousands of
the following errors:

Expecting top ca1e, got ff00

zttool shows over 5,000 IRQ misses.

Is this expected behavior when there's no active PRI going into the card? 
If so, great.  If not, I'd like to isolate (and fix) the issue before
wasting my PRI provider's time during turn-up.

Thanks,

Brad Waite
