Using the driver from HEAD* in the latest RELENG_6 didn't fix our
problems.
We could still trigger the Watchdog timeout when copying a local file to
an NFS mounted filesystem (UDP mount, GigE speeds).
It was also possible to trigger this bug with multiple simultaneous TCP
streams, but that took a little longer.
Copying a local file to an NFS/UDP filesystem would trigger the bug in a
few seconds.
If there's anything we can do to help debug this, please let us know.
