A wee while ago, USB support on FreeBSD6.2 SMP systems was discouraged. Is that still the case?

Thanks Garrett.

By the way, my colleague informed me incorrectly that USB and SMP 
support was an issue. (Although I am keen for this to work!) :-)

 From the latest source, the Kernel PAE conf file mentions that USB and 
PAE are not known to play well together. This is my immediate concern.

I presume giant-locking is one mutex that rules them all? As such, 
besides being inefficient under load, how would running USB under this 
be a problem with PAE?

Cheers,
Brett.
