Yep, that's it. On my system, something sets the L2CAP MTU to a
whopping 48 bytes, and the code below, from l2cap_core.c,

	switch (chan->mode) {
	case L2CAP_MODE_BASIC:
		/* If socket recv buffers overflows we drop data here
		 * which is *bad* because L2CAP has to be reliable.
		 * But we don't have any other choice. L2CAP doesn't
		 * provide flow control mechanism. */

		if (chan->imtu < skb->len)
			goto drop;

silently ignores packets larger than that value. Duh.
