The most evident trouble happens while unloading the modules, either on shutdown or doing simple modprobe -r or rmmod. The system hangs completely. On my P4/SMT machine it doesn't spit anything out to the serial console. Nada. OTOH, on my P4/UP laptop, I found that it does behave a litle more verbose, as the following syslog excerpt: Nov 6 20:29:52 lambda alsa: Shutting down ALSA sound driver (version 1.0.6): Nov 6 20:29:55
