This error (ENXIO) is expected.

What I don't understand is EBUSY at the following error message.

	altqd: can't open altq device: Device busy

It's from tbr_install() in libaltq/qop.c at open(/dev/altq/altq, O_RDWR).
The corresponding kernel code is altqopen() in sys/altq/altq_conf.c,
and it always returns 0 for opening /dev/altq/altq (cdev minor 0).
