I would try upgrading to 6.3R (there are several em driver bug fixes)
and then try the box with
% cat /boot/loader.conf
hw.pci.enable_msi=1
...if the cards support msi.
I think pciconf -lvc should tell you if the cards and slots support it or not.
Also, if you dont need IPV6, use FAST_IPSEC. It does not need
mpsafe. If you do need IPSEC and IPV6, 7.0R got rid of that restriction.
