 Apart from the problem described by davidch@ (I'm not sure
 you actually have a BCM5701 A3 though, at least bge(4) doesn't
 seem to be aware of that revision) the BGE_PCI_PCISTATE and
 bge_flags pairs you reported don't match though; according
 to BGE_PCI_PCISTATE the card isn't in a PCI-X slot in either
 case (BGE_PCISTATE_PCI_BUSMODE is always set, which means
 PCI) and AFAICT your motherboard chipset also doesn't
 support PCI-X. However, as you noted BGE_FLAG_PCIX is set
 for whatever reason in both cases, which leads to some
 inappropriate initialization of the controller. As a quick
 test could you please check whether replacing the "#if
 __FreeBSD_version > 602101" in the driver with an "#if 0"
 makes any difference to your problem?
