I've just setup a lab in the office to test out IPVS, and I'm using an Asus
p5q-ws MB with dual r8169 nics on board. This machine is acting as a load
balancer, and it's just directing packets to the web servers. Lots of
requests...

After about 20 minutes of hammering it with two servers running apache
bench, I too get the r8169 time out. It causes a temporary hiccup.

Running 2.6.28.1 on centos 5.2 x86_64. It just dropped the connection
again, as you can see in /var/log/messages, but there was no kernel panic
with this one.

Does it translate into a temporary network hiccup, say a few seconds,
or does it mean a final loss of networking ?

Given the timestamp, the driver seemed to worked for some amount of time
before breaking, did it not ? It would thus be different from the usual
"no link at startup" problem.

Can you send a complete dmesg, including the r8169 XID line ?
