I grabbed these updates and applied them cleanly to stable/9 on a Dell
R620 with a quad port BCM5720, I still see watchdog timeouts and reset
indications.  I am able to ping out of the box for a short amount of
time before the device hangs and times out.

The stats counters don't really show much here, but here they are
regardless.
