Description of problem: Have been using iptables as a host-based firewall for some time. Made a minor mod to open access to internal network. Now, system consistently hangs during boot when setting up this new iptable configuration. Version-Release number of selected component (if applicable): iptables v1.2.9 kernel: 2.6.9-1.6_FC2 or 2.6.5-1.358 How reproducible: 100% reproducible. Note: kernel has specified: acpi=off netprofile=XXX Steps to Reproduce: 1. Configure iptables as per attachment. 2. Reboot 3. System hangs Actual results: system hangs Expected results: system boots Additional info: Once the system has booted, I can manually configure iptables and the configuration works. I can also start and stop iptables however many times I like using the saved tables that hang at boot. To work around the problem, I simply disabled start of iptables at boot and mamually start them whenever I reboot. I have done a verification of all system packages, and everything checks ok.
