.. and if this is a problem, a boot -v from both releng_7 and releng_8
would be a good starting point. Surely detecting the CPU cores would
be an easy thing to get right. Also, it may be a hyperthread CPU
"thing" - I recall some changes in the releng_8 timeframe because of
security vulnerabilities with classic hyperthreading and you have to
do something to enable it again.
