eth0 not working [Resent after 8hrs]

It may be because it's late but I can not for the life of me get eth0
talking to
anything. It works under gentoo's livecd and it worked before then in
all the
other distros I ran. I can even restart to the livecd and it works. In
dmesg, I
get alot of net watchdog: eth0 transmit timeout but also mii-tool does
negotiate
(successfully) with the switch.

Help!
