Subject: tg3 link state detection

With 2.6.8(.1)+the add_pin_to_irq fix we're seeing problem with link 
state detection using tg3 devices. The network in question has a severe 
case of cable monkeys, so the link is a bit jumpy.

 From time to time the tg3's do not detect that the link is up again, 
and thus has to be rebooted (ifdown/up has not been tested due to 
triggerhappy non-technical on-site monkeys.)

Is this a known problem?
