I'm not quite -current at the moment and there are a changes from the last
few days that affect both SMP and CAM.  (Catching up right now.)

However, my experience with a dual-PII and a 3940AUW (are you sure that
your card isn't one of these, rather than a "2940 dual card"?) has not
demonstrated the problem.  I am not running any external devices, however,
which is probably the key to the problem.   

You might re-cvsup because I think there were some aic7xxx changes this
morning, and you may have also missed an SMP/VM commit from yesterday.
