I can also verify that I have no sound with -24 & reverting to -22.1 I have sound again. the downgrade was "messy" due to bootlogd. Looking at -24, I see that many things are changed in mountlocation. I also note that during a verbose boot I get modprobe information with -22.1 & don't get the same info.
