tg3 driver problem on gige networks?

[Brown, Rodrick R]

I'm having an issue with a server running 2.6.9-34.ELsmp with the tg3
driver, periodically it will become unresponsive no rx/tx packets are
transmitted then it will magically come back online after about 10 - 30
minutes, currently flow control is disable on this sever its running at
1000 FULL auto. 
 
I have two questions how does one enable NETDEV watchdog? I notice the
absence of this facility on my server, and also is it possible to add
more verbosity to the tg3 driver messages/notifications. 
 
Any added information would be appreciated thanks.
