iptables OOPS (all recent kernels on x86_64)

From: David Ford
Date: Mon Nov 15 2004 - 01:32:42 EST


Up until 2.6.9, when I changed link status after the initial configuration, I would get a kernel OOPS. Now with 2.6.9, I get a crash immediately on boot with network device configuration. Attached is my boot log.
