Yah my undestanding here / & cursory peek at the wblah drivers is that
the digium driver implements all processing
during the interrupt  including the echo can work, the sangoma driver acks
the irq
& defers the processing to another task so are irqs NEVER dropped on the
floor
like the digium drivers....
It would be nice for Mark to comment on this design flaw ...?
