[Sorry for duplicate posting, I've used the wrong list address.]
I suppose the NIC in the PowerMac G5 can do GigE, yet when plugged into a
GB switch it is only willing to talk 100MB with it. Any idea why? Kernel
is 2.6.16-rc5-git2.

Works for me... Must be a problem with auto-neg and your switch, or the
cable.... Can you check how the switch is configured maybe ? You can
also try forcing the link speed with ethtool.

It's not the cable, I have swapped it with another system where Gb is
working fine. Neither it's the switch port, I have swapped it too. I
can't force the speed with ethtool either. Any other idea what to look
for?

At this point, all I can say is... does it work in OS X ?

Strange, OS X can't do it either. Looks like I have a hardware problem.

It turned out that one of the contacts in the RJ-45 jack was twisted.
After straightening it the Gb connection is working now.

It does 1000Mb/s here...
