Your original message was two months ago, so this is probably too late for you,
but:
Some combinations of device and bus hardware do not like PCI IO modes
enabled, so try setting the sysctl variable
hw.pci.enable_io_modes="0"
in /boot/loader.conf or /boot/loader.conf.local and rebooting.
Or
The Realtek 8139 cards are a pretty cheap chipset that many others
have had problems with. Try a different card from a different
manufacturer.
It is probably some BIOS setting in your motherboard. You might try
setting
the board to non-pnp OS to allow the board to assign resources.
