"I have a PowerBook G4 17" 1.33GHz, and am having a rather strange 
problem.  Whenever my Mac wakes from sleep, all network connections 
dead, and can only be resuscitated by rebooting the machine.  I have 
tried the usual remedies of switching locales, downing and upping an 
interface, and switching from DHCP to static IP, or vice-versa."

What is the system connected to? Could the problem be with the other 
end of the ethernet segment?

I once had a similar problem with the ethernet interface on a Powermac 
G4. I traced it to a faulty implementation of spanning-tree protocol on a 
3Com switch (when the system woke from sleep, the switch thought it 
was detecting a a loop in the switch fabric).
