I found much the same thing; specifically, the problematic change is this one:

jhb         2001/08/10 14:08:57 PDT

  Modified files:
    sys/kern             kern_synch.c 
  Work around a race between msleep() and endtsleep() where it was possible
  for endtsleep() to be executing when msleep() resumed, for endtsleep()
  to spin on sched_lock long enough for the other process to loop on
  msleep() and sleep again resulting in endtsleep() waking up the "wrong"
  Obtained from:        BSD/OS
  Revision  Changes    Path
  1.154     +24 -4     src/sys/kern/kern_synch.c

Kernels built from source immediately prior to this change work; kernels 
built from source immediately after this change have the sound-related problems
mentioned in this thread.
