FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Creative EMU10K1> at io 0xcc00 irq 10 (4p/2r/4v channels duplex default)

>Description:
	When attempting to `kldunload snd_emu10k1`, my system panic'd with
	"don't do that"

	After looking at kernel source, it looks like this is related to
	pcm not properly dealing with devfs. See destroy_dev() in
	sys/kern/kern_conf.c

>How-To-Repeat:
	1. Load snd_emu10k1.ko
	2. Unload snd_emu10k1.ko
	3. Watch in horror

>Fix:
	Make pcm use devfs properly? Still investigating.

 This PR can be closed. I no longer see this behavior and most likely
 haven't for a long time. I just noticed this was still open (and untouched)
 when going through my PRs.
