Description Jon R. Kibler 2005-01-03 19:59:38 UTC
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.
