Yeah, my gut reaction was that this was something to do with the recent em changes rather than BPF. I don't think the BPF code has changed recently. BPF is hooked into network interfaces pretty directly, so if some packet data was being freed too early by a race condition, this seems like a conceivable way we'd find out. My speculative 2ยข.
