It interacts quite excellently.
There was a long saga about this with tg3 and huge SGI numa systems with large costs for interrupt processing, and the fix was to do a minimal amount of interrupt mitigation and this basically cleared up all the problems.
Someone should reference that thread _now_ before this discussion goes too far and we repeat a lot of information and people like myself have to stay up all night correcting the misinformation and misunderstandings that are basically guarenteed for this topic :) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
