During a kickstart install of CentOS 6 to a client with an Intel 82574L NIC, this NIC will stop responding at some point during the install. This is remarkably similar to <a href="http://bugs.centos.org/view.php?id=4371">http://bugs.centos.org/view.php?id=4371</a> [<a href="http://bugs.centos.org/view.php?id=4371" target="_blank">^</a>] <br />

A freeze-up was happening while downloading the install.img from the kickstart server. Sometimes this would occur right away, 4% or so. Other times it would make it to 70% and die. I got past this by setting net.core.netdev_max_backlog=3000 on the server side (CentOS 5.7) but this just causes the install to fail at a later point, when it says it's unable to retrieve repo metadata from the server. A check of the server log shows no requests are even coming in.
