While trying to debug this problem, I've noticed that though I can recompile
snd_hda(4), I cannot load it:

    # kldload ./snd_hda.ko
    kldload: can't load ./snd_hda.ko: No such file or directory

The message is clearly bogus, but in /var/log/messages I see this line:

    link_elf: symbol snd_verbose undefined

Is this known behavior?  How to remedy it?
