A piece of my syslog is shown below.  While this stuff was going on that
machine was disconnected from the network.  I stopped and restarted dhcpcd
and eth0 a few times trying to get it back online.  The third time I tried
"ifconfig eht0 down,  ifconfig eth0 up" it started working again, but I'm
not sure I fixed it, or what was wrong.  I may have rmmod'ed the 3c59x
before it started working too.  I should take better notes next time.  I
also moved the patch cord to another port on the same switch.
It might have been something to do with RoadRunner.  It could ping out to
the RR gateway, but not beyond.  However, I get two RR addys and they just
happen to be on the same IP subnet.  The other one had no problems during
the same time.  Also, it seems unlikely a problem with their router would
have confused my NIC this way.
It's a 3c59x NIC.  2.4.8-26Mandrake stock kernel.  Let me know if you
need any other info.
Any clue what happened here?  How to keep it from happening again?
Thanks,
Greg
