When the kernel environment goes to dynamic from static hints mode, the a
bug in the resource_xxx lookup routines prevent them from using the dynamic
environment. So they only report as of the static environment, while the
kenv related routines report what's in the new environment. This can lead
to very messy symptoms.
The subr_hints.c file tries to detect when the kernel environment changes
state. But there's a bug in that. Update below has been tested.
