We have placed a Linux bridge to isolate the Internet from the campus. To nullify network flooding effect, we have used iptables. The kernel is 2.6.0-test9, the ethernet cards that are used are RTL8139. The problem is : After 3 to 4 hours of functioning, the bridge stops working and the machine becomes unusable where it doesn't respond to keyboard, and there is no video display. In simple terms it freezes. Before going in for 2.6.0-test9 I have tried 2.4.20 with bridge patches for iptables support. It worked reliably except that I cannot even login from the console because I don't get the shell prompt after a while. Presently I have gone back to 2.4.20 for the sake of robustness. Can someone let me know what I can do to use 2.6.x kernel with a good amount of confidence so that I can keep the campus users happy ? I am making guess work as to whether the problem is with the network drivers, or some power management issues, and so on. Any inputs from you will be really useful. I am eager to try out any amount of debugging, the thing is I don't know what to look for. Anand
