    sys/kern             subr_hints.c 
  MFC 1.12 (by netchild)
  | The resource_xxx routines in subr_hints.c are called before and after the
  | kenv environment in kern_environment.c switches to dynamic kenv. The prior
  | call sets the static variable hintp to the static hints in subr_hints.c
  | (hintmode==0).
  | However, changes to the environment are not detected by the resource_xxx
  | lookups after the change to dynamic kernel environment, so the lookup
  | routines only report the old stuff of hintmode==0, even after the change to
  | the dynamic kenv. This causes kenv users to see a different environment than
  | the kernel routines.
  | This is a problem in the mixer.c code that looks up initial mixer volume
  | settings from the hints: If the hints are dynamic and not from the
  | device.hints file, mixer.c doesn't see them, but kenv does.
  | The patch from the PR (modified to comply to the style of the function)
  | solves this.
