Thanks. /var/run/dmesg.boot says my em0 and em1 don't share an IRQ with USB or anyone else, so sounds like I'm in the clear, yay. But it still seems like something the vendor (Intel?) should be looking into before a another release on RELENG_6 is cut - even if USB is the culprit, it sounded like the problems started for em users when the driver was updated from 6.2.9 to 6.6.6.
