[PC-BSD Testing] Kernel Panic on Wireless + shutdown

I should have checked this list too..

there are quite a few services that are not needed and I believe that most 
of the average people will never user, for example SNMP, old HP printer, 
FVCOOL???, lircd .. those, in my opinion, should be in the service list and 
allow only people that want to turn them on to do it.

what you guys think about it?
