Sorry guys for not being available in the last few days...

prado: libpri version is 1.4.11.3

odvel: while the span is OK, I can place calls and I have no problems
(only the "PRI got event: HDLC Abort (6) on D-channel" warning). Then, when
the span goes on RED, I can no more place calls.

sruffel: I tried to use irqbalance to force all wcb4xxp interrupts onto
one core, but it doesn't work (I see other modules onto that core). I'm
trying again now.
