Public bug reported:
My wired network card stops working from time to time. Bringing the
interface down then up again doesn't solve the problem. Rebooting the
laptop does solve the problem sometimes. This is really random, and I
don't know yet how to reproduce it.
Here's a sniff from kernel log:
Feb 16 10:49:25 daniel-laptop kernel: [17179732.132000] NETDEV WATCHDOG: eth0:
transmit timed out

I have also seen a similar behavior on bug# 76489. Just when I wanted to
try the workaround suggested there, the network card started working
again.
Here are the specs:
