I'm having trouble modprobe'ing the alsasound drivers ever since
RT-V0.7.11, to latest RT-V0.7.18, and I suspect this applies to -mm3 as
well.
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:
