No, I do not see this message.   I do see a driver message in the kernel:

Jun 17 08:43:04 localhost kernel: eth1: link up, 100Mbps, full-duplex, 
lpa 0x41E1

I'm using the 8139too driver.  I notice that it shows full link
speed (100-FD) when the NIC is admin down.   Maybe that is causing it to not
go through an expected state change?

I'll work on doing this same test with a vanilla kernel but on this 
hardware just in case I've
screwed something up somewhere...

Thanks,
Ben
