Subject: 3.4-rc: NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out
Hi,
I switched from 3.3 to 3.4-rc5 yesterday and am getting the following warning
some time after boot (e.g. this time about two hours after boot). What's up
with that?

I do not remember such messages from any earlier kernel.
There are no noticeable issues, but I don't run anything demanding on the
interface right now which would make any downtime obvious.
It is an RTL8168(?) on an Asus M3A78-EM motherboard.
