Using the driver from HEAD* in the latest RELENG_6 didn't fix our

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.
Per my previous mails, the (known) bce watchdogs are symptoms of
driver bugs which can be usefully converted into panics by enabling
INVARIANTS and INVARIANT_SUPPORT. Please do so, then report what
happens.

Hi Kris,
I am a colleague of Jason's, when we were testing this patch the kernel
used had both options set:
option INVARIANTS
option INVARIANT_SUPPORT
Although on several boxes we have failed to cause a kernel panic, only
watchdog timeouts. However the last crash that we reproduced did
trigger several:
bce: need to defrag
Messages on the console before the watchdob timeout occured.

This is a debugging message that I accidentally left in. It may relate
to the problem, I'll take a look.
