1. Recompile kernel implementing "device pcm, device sbc0..." change
2. Reboot and log on as root.
3. Type "startx" to go into KDE. Wait till hear music from KDE successfully 
starting (shows main GUI screen).
4. Open up a console windows and type "kldload snd". Wait till the snd 
modules load.
5. Type "kldunload". See if it cleanly unloads the snd modules or crashes 
your system.

I originally did this test with the GENERIC kernel without recompiling. The 
test completed successfully. I recompiled my kernel to get the sound working 
like I always do - nothing different. I tried the test again and when I 
typed kldunload the system locked up and rebooted. I was rebooted the second 
time I tried to start KDE after the first reboot. The third time I restarted 
KDE, I could get into KDE successfully.

Don't do this at home, kids.

Ken
4.4RC5
