--- Comment #6 from Rodney W. Grimes <rgrimes at FreeBSD.org> ---
I just noted this in your original report:
    The light on the workgroup switch shows a 1GBit link,
    but will turn off and on again occasionally.
    (Some form of reset seems to be going on.)
That is indicative of a NIC reset and re-negotiate, that can cause the
switch to be deaf/mute on that port until it redoes STP.  Please if you can
turn STP off on the port of the machine having issues.

I also would like to ask:
Are you using the PXE client in the broadcom BIOS?
Are you using any VLAN taggging stuff?
Is this NIC in use as a shared IPMI device?
