If your network irq handler has a higher RT prio than the soundcard irq handler, xruns are preprogrammed. If you run RP make sure that: a] the soundcard irq has the highest prio in the system (i.e. around 90) b] all other irq's are left near their default (around 50) c] jackd's prio is inbetween (i use 70 with great results) If you then still get xruns, the hw is to blame [imho]. Or maybe a bug in RP patches. Use the latency diagnosis tools that the RP kernel provides to find out what part of the kernel produces the delays.
