Description Alex Schultz 2004-03-08 12:19:51 UTC

When i try to enable the iptables/net filtering options in the 2.6.4-rc1 kernel the kernel compiles fine.  However on reboot I get a kernel panic when it attempts to start up apache2. I will include the Oops message, a broken config and a working config.

Reproducible: Always
Steps to Reproduce:
1. enable net filtering in the kernel 2.6.4-rc1
2. genkernel, grub, reboot


Actual Results:  
Kernel panic

Expected Results:  
The system should have booted without a kernel panic

Since we don't maintain the upstream sources; we can't do much about the issue. Can you file a bug at http://bugme.osdl.org which the upstream kernel developers would sort out?

Thanks!
