when you boot, at the FreeBSD menu, break to the command prompt and  
type this:


and see if it works.  I have one system on which 5.4 works  
flawlessly, but anything from 6.0-REL and up requires I disable the

If it works, just add the above line to your /boot/loader.conf file  
to make it stick across reboots.
