Subject: Re: 2.6.29 on MacBook 2,1 fails to reboot

I have more information on this.  I put an strace in the shutdown
script for alsa sound...

strace -T -f -o /root/${1}-strace.txt rmmod --wait "$1"

${1} is the module name...

Oops, I just noticed that it finally quit.  Some of the modules were
unloaded successfully, others, after several minutes, got an error.  I
have the strace for all of them if you want it.  But, here's an
example.  Note the end where it says "resource temporarily
unavailable".  I also give a second strace snippet after this one...
