Complete loss of network on 6_STABLE

[Drew]

A little more on this, because now I am really stumped. I have taken known
good source, and moved it via CD to this machine. I rebuilt, and it exhibits
exactly the same behavior, with both my kernel, and GENERIC. Pinging an IP
on my lan results in ping: sendto: host is down. There are no active
firewalls on this machine. When I ping another IP on the network, activity
happens on the switch. I have swapped NIC's to a known working one from
another machine, and it behaves identically. I have changed ports on the
switch. About the only thing I haven't done is reinstall (which reminds me,
I have a Freesbie disc around here somewhere to try) - but I'd rather that
was a last resort. Meaning I'm open to any suggestions anyone might have
about this.
