[Asterisk-bsd] TDM410P interrupt underruns with wctdm24xxp

[Ian FREISLICH]

Hi

I experience these interrupt underruns on my TDM410P card with the
wctdm24xxp driver and bad echo as a result.  My motherboard has 2
PCI slots which share an interrupt between them.  If I swap this
board for a TDM400P using the wctdm driver everything works properly.

I note that wctdm0 registers the interrupt:
wctdm0: [FILTER]

but, the wctdm24xxp0 doesn't do this, but I can't find where the
irq is registered for the wctdm24xxp driver.
