Ok, I've tried that.  I removed sound.ko and snd_mss.ko from 
/boot/loader.conf, rebooted without sound support, and did 
suspend/resume.  Upon resume, FreeBSD locked up, requiring me to turn 
off the system to recover.  Now what?  How do we continue 
troubleshooting with no error message and no core dump?

Thanks,
Dave
