Sorry - I meant to include it and left this one out:  (note that when I  
restart the network the 1 GB card restarts as a 100 MB, not 1GB,  
card...),  Almosting nothing really - here's the only entry from the  
logs (and this set of 3 occurs only ONCE over several days...):

Feb 27 00:47:38 dsl027-161-055 kernel: ADDRCONF(NETDEV_UP): eth0: link  
\is not ready
...
Feb 27 00:51:16 dsl027-161-055 kernel: e1000: eth0:  
\e1000_watchdog_task: NIC Link is Up 100 Mbps Full Duplex
Feb 27 00:51:17 dsl027-161-055 kernel: ADDRCONF(NETDEV_CHANGE): eth0:  
link becomes ready

Again, this one has me stumped (I've been running linux boxen at home  
and at the office for many years and this is a new one to me...)

Thanks.
