Under unknown circumstances one of a few major connectivity issues have
occurred, usually accompanied by no easily distinguishable sign except that
network communication (except, on occassion, icmp packets) are not transmitted
nor recieved via the gateway address.
For example, machines within a local network will be accessible while the
machine cannot access the outside world (and vice-versa).
On at least 3 of these occassions the problem was related to a netmask
automagically changing itself, and in the remaining cases everything appeared
correct (including the netmask).
As of this point it has only happened on my boxen with 3Com NICs using the
gentoo-sources patched kernel, the server with a vanilla-sources kernel and an
Intel NIC has not experienced this problem as of yet.
... Enjoy, it's left me stumped.

This is what route outputs when external network communication problems occur.

This is what lspci outputs, listing the network card.
If you want me to grab any information, just ask.
May i ask do you intel cards push-pull alot of data? or do the 3coms do all the work? or do they all work hard?
well, cannot reproduce and there is not enough info to go further.
Looks like we have Bugzilla database issues, bumping bug back to original
