[CentOS] Eth1 problem on CentOS-6.3

I am trying to transport a dd image between to hosts over a cross
linked gigabit connection.  Both hosts have an eth1 configured to a
non routable ip addr on a shared network.   No other devices exist on
this link.

When transferring via sftp I received a stall warning.  Checking the
logs I see this:

dmesg | grep eth

This may, or may not, be related to this bug:

https://bugzilla.kernel.org/show_bug.cgi?id=12411

Is there some way to confirm whether or not this is the case.  Is
there a work-around for it if it is this bug?  If it is not then has
anyone any idea what is happening and how to fix it?
