Ugh! This has been an issue since xen was incorporated and was the source of many a mail well over a year ago, not that I can actually find any of said mails (I think they were all mine anyway ;).
From memory (and mine isn't the best), whenever a new interface was added it was like the bridge reset and I think it effected all attached interfaces for a short period. It may be part of a relearning process? Either way, don't use the stp option unless it's required :)
