If eth1's netmask , it'll try to send/receive stuff for
everything in the net.  Since eth2 is *also* inside ,
wouldn't that cause problems with routing, like routing all packets destined
for through eth1?  Is eth1's netmask set appropriately?  The
network config here just looks like it'd cause odd failures.  What's the
config look like on the second box?  You said the second box was working

(Why yes, I've done "ifconfig eth1 up" and completely hosed all
networking on a test DRBD box, since it should've been "ifconfig eth1 netmask up"....)
