/dev/dsp busy

[doug at safeport.com]

Alas no - thank you for the suggestion. Following your lead I tried a number of
variations including turning ACPI off, any some other sysctl setting I found via
google. All with the same result.

Next I removed load command from loader.conf and rebooted. No kde, no X server.
I then loaded and tried to unload the sound modules. sound.ko would not unload
presenting as busy. Is this a problem? It was suggested to me interrupt problem
at startup could cause this. I get the same result in single user mode.

My commands:

# kldstat
Id Refs Address    Size     Name
 1    7 0xc0400000 5cdad0   kernel
 2   14 0xc09ce000 537f0    acpi.ko
 3    1 0xc1675000 17000    linux.ko

# kldload snd_maestro
pcm0: <ESS Technology Maestro-2E> port 0x1400-0x14ff irq 5 at device 8.0 on pci0

pcm0: <SigmaTel STAC9721/23 AC97 Codec>
pcm0: [GIANT-LOCKED]

root at mneme:~# kldunload snd_maestro
pcm0: detached
# kldunload sound
kldunload: attempt to unload file that was loaded by the kernel
kldunload: can't unload file: Device busy

I am assuming that the above means this is not a KDE problem. Is this correct?
