I did something similar when I hooked up 3 of my Linksys boxes (modded
with OpenWRT). They are running distributed wireless mode (WDS) in
order to expand the reach of the wireless netowork and I forgot to
enable spanning tree protocol (LAN_STP=1).

Apparently some loops were created within the Linksys's and it made
the switches go crazy. After enabling STP, everything was better.

This happened the other day at my work.  I thought it was kind of
amusing.  When the ARP of death hit my laptop (win2k) hit about 60%
utilization.  I noticed the lights on my dlink switch were going nuts
with activity.  A quick look in wireshark revealed the network was being
flooded with ARP's.  The computer from which the ARP o death originated
(winXP) had locked up.  It actually no longer booted and we had to
reinstall it.  Even after disconnecting the origin of the ARP from the
network we were still flooded with the same ARP request.  A couple of
other XP boxes kept flickering their display like they wanted to "blue
screen" but couldn't make up their mind.  The linux machines seemed
unaffected except for the network traffic.
