[Bret Ketchum]

    Syslog suggests the interface is brought down then up but no interrupt at 
the irq assigned. Need to enable more debug and make sure the interrupt is 
wired properly.

Maybe irq gets asserted, but guest does not have a handler?
Take a look at system log, that might give some hints.
