Check the duplex settings in ifconfig(8) output on all three machines.
They should all say:

   media: Ethernet autoselect (1000baseTX <full-duplex>)

assuming you're not forcing everything to a particular speed.  Any
mention of '100baseTX <half-duplex>' indicates a failure to negotiate
the link settings, which could well be due to a hardware problem.  Mind
you, in that case you'ld see plenty of errors in the output of 'netstat -=
i'

If that's not the problem then it sounds like you've eliminated all the
obvious causes.  Which means a bug in 9.0-PRERELEASE, so please bring
this up on freebsd-current@... where it should come to the attention of
the developers working on getting 9.0 out of the door.  Include 'pciconf
-lbv' output for the NICs and PHYs on all three machines if you would be
so kind.

	Cheers,

	Matthew
