Log Message:
My 16 port boca seems to fail to update the interrupt bit in it's interrupt
register for a port under high load. The effect is that the port is wedged
waiting for an interrupt that will never come.
Add a callout-based watchdog which periodically (hz/10) scan trough the ports
for missed interrupts.
Problem also noted by Chris Jones, and this fix also helped him.
